Undefined function or method '...' for input arguments of type 'double'.

I'm getting the following error when I try to run some function m-files: ??? Undefined function or method '[name of function]' for input arguments of type 'double'.

I know this usually happens when the file isn't in the working directory, but that's not the case here.

When I was running these m-files in a different directory on my computer, it worked fine. I moved them to another directory on my laptop, and they're still fine, but I get this error on two of my desktops.

Thank you.

I am pretty sure that the reason why this problem happened is because of the license of the toolbox (package) in which this function belongs in. Write

which functionName

and see what will be the result. If it returns path of the function and the comment

"Has no license available",

then the problem is related to the license. That means, license of the package is not set correctly. Mostly it happens if the package (toolbox) of this function is added later, i.e., after installation of the original `matlab`. Please check and solve the license issue, then it will work fine.

I am actually facing this problem too as my inpoly function is running accurately before installation of a new matlab but now I am running the same code with old file of poly function but it is showing the error of undefined inpooly function. Kindly tell me how to resolve the license issue as I have also checked my code by intalling new function of inpoly but the problem persist. Kindly help in this matter.

Walter Roberson on 20 May 2018

inpoly is not a Mathworks supplied function. https://www.mathworks.com/matlabcentral/fileexchange/10391-fast-points-in-polygon-test

Answer by Majid on 12 Aug 2013

In my case, there was a function that is used in my code but it was not in the directory, so by changing the location of the sub function and copying in the active directory , the problem is solved now.

Walter Roberson on 25 Jul 2016

Use your operating system tools to copy the directory and then use pathtool to add the new location to your MATLAB path.

change the working directory to the folder where you have your code or add the path.

Go to the File and choose the Set Path

Answer by Keith Kripp on 10 Jun 2013

I've encountered this error when attempting to call MEX functions that were built/compiled on machines running a different version of Windows.

e.g. I build a MEX file from source code on a 32 bit machine, transfer it somewhere down the road to a 64 bit machine, and then attempt to call the function.

Seems like this error often has little to do with the arg type being 'double.'

1 Comment

Matt J on 10 Jun 2013

Seems like this error often has little to do with the arg type being 'double.'

Well, sometimes it genuinely is an issue of the arg type, as shown here

>> sin('a')
Undefined function 'sin' for input arguments of type 'char'.

Clear 'sin' does exist, but just doesn't know what to do with char input.

As for the MEX-file issue, that has nothing to do with the 64bit-ness of Windows, only the 64bitness of the MATLAB version. 64-bit MATLAB will be looking for files with extension 'mexw64' whereas a 32-bit compiled mex file will have extension 'mexw32'. So, that really is a case of MATLAB not being able to find a matching file.

Answer by Devi Jorks on 18 Jul 2013

in case of the sin(a) just dont put the '', then it works fine, at least on winxp 32bit

Answer by chao dong on 21 Mar 2016

For me,the reason why this error occured was because I used a method that actually did not belongs to the object I used to invoke.This means that I should first transform my object to another type of data,for me,I actually have to change the object belongs to vehicle class to mini class to specify its data type. OOP's philosophy is indeed very important for you to understand why it occured and solve the error.

Can anyone help me with this error?

1 Comment

Walter Roberson on 10 Aug 2016

Mathworks does not define a function named "wavelet" in any toolbox.

I checked and it does not appear that any of the File Exchange contributions happen to define a function with that name either.

You appear to be using the code from G08isu.pdf. It appears to use software from colorado.edu; it looks like you can find the source code at http://paos.colorado.edu/research/wavelets/software.html

I met the problem ??? Undefined function or method 'cdfcalc' for input arguments of type 'double'. Besides, when I use cmd "which cdfcalc", returned that no such a function found. I wonder if I missed to install something?

Plus: When I went to the download page, I have these to download: Installer.exe MATLAB77.zip Communications_Toolbox42.zip Signal_Processing_Blockset68.zip Signal_Processing_Toolbox610.zip

I downloaded them all and installed. But when installing, it alerted me that no Simulink. How should I handle this?

1 Comment

Walter Roberson on 11 Oct 2016

cdfcalc is from the Statistics and Machine Learning toolbox. It appears that you have not installed that.

The Signal Processing Blockset that are trying to install requires Simulink and is useless without Simulink. It does not affect use of the Signal Processing Toolbox by itself, so you should only install Signal Processing Blockset if you install Simulink.

If you have a Student Suite license, then you might simply have not told the installer to install those packages.

Answer by 0460051 NCTU on 11 Oct 2016

I have the same problem.Here is my error.

An UndefinedFunction error was thrown on the workers for 'configurePin'. This might be because the file containing 'configurePin' is not accessible on the workers. Use addAttachedFiles(pool, files) to specify the required files to be attached. See the documentation for 'parallel.Pool/addAttachedFiles' for more details.

Caused by: Error using parallel_function>make_general_channel/channel_general (line 929) Undefined function 'configurePin' for input arguments of type 'double'.

I'm trying to communicate matlab and arduino.However, it's always running wrong.What's happened?

As the getsnapshot documentation clearly states, its input must be a video input object. Your error message tells us that you are not giving getsnapshot a video image object, but a numeric value. You need to give it the right kind of input (the one that the documentation tell you that it requires).

Error:Undefined function ‘execute’ for input arguments of type ‘double’.

raspberry pi simulink

Causes

Actually this can happened by many problems, one of them could be, the Simulink Support Package files didn’t downloaded correctly and may be there are missing file, and to be sure of that write:

which functionName

for example which execute

and see what will be the result. If it returns the comment “Has no license available” or just gives error , then follow the below soution and if returns with path and a name of the file ,then restart your matlab and check ,if not solved it could be another problem.

solution

Download all the package again, but before doing it, you have to remove SupportPackages folder in the following path: C:\Users\your_pc_ userrname\Downloads\MathWorks and start downloading the package ,it will works and mathworks will download the all the rquired files in that path for size not less that 716MB

i just restarted my pc and matlab and every thing works well ,thanks to these maklab team people http://www.maklabacademy.com/error-simulink-support-package-raspberry-pi-hardware-2016-2017/

If you're trying to run the example from this blog post, you will need to download this File Exchange submission. I recommend using the Add-Ons manager to add it to your MATLAB installation (search for "deep learning 10 lines") or you can download it and manually put it in a directory on your path.

Note that the requirements state this requires Image Processing Toolbox and Neural Network Toolbox, so make sure you have those products installed.

Answer by Metin Ozturk on 31 Jul 2018

It may be because the function you are trying to use is not available in your current MATLAB version. For example, if you use 'normalize' function in any version other than 2018, it will produce the same error, as the 'normalize' function was introduced in MATLAB 2018.

ziegler_nic is an internal function to pid_design of https://www.mathworks.com/matlabcentral/fileexchange/18-ctrllab

You would not be expected to call this routine yourself, and if you did call it then MATLAB would not be able to find it because it is internal to the other function.

Answer by clpi on 3 Jul 2019

Hello !

I have a matlab function which at a certain point calculates sin(2*pi*freq*t_array) (t_array in an array of size (1,2000).

I tried to call this function vi matlab.engine but I got the error message: "Undefined function 'sin' for input argument of type 'int64' "

I tried what is people suggested in this topic but it didn't work. I wanted to add the file 'sin.m' to my working directory but it is not a function script, it is a simple text.

I would be very grateful of any help

Thank you !

1 Comment

Guillaume on 3 Jul 2019

Please start your own question if you need help. sin is indeed not defined with inputs of type int64. Convert your input to double. If your number is so large that it looses precision when converted to double (i.e. it is greater than flintmax) then why are you calculating the sinus of such large numbers?

You are now following this question
