Make error when using a embedded matlab function

Asked by Anand
on 28 Mar 2013

I wrote a simple function to swap variables. I am using MATLAB in Win 7.

function [x,y]= swap(u,v)

I get a make error stating

 "Making simulation target "ex2_sfun", ... 

C:\Users\....(some location)>"c:\users\(some location)" -f ex2_sfun.lmk The system cannot find the path specified."

I get Parse Ok and Code Ok.

What might be the problem? Please help me.

Okay, the pronlem could be that you are missing System32 on your PATH variable. Could you make sure that "C:/Windows/System32/" exists on your machine and add that to the System PATH environment variable? Then restart MATLAB and try your model again.

Hi.. By System PATH u mean the Path variable in Environmental variables of computer properties? I added in that and still it not working. Again it is giving me Make Error.

Now, when you run "getenv PATH" from MATLAB, does "C:/Windows/System32/" show up in the list?

Probably there is a simulink model with the same name. Try to use a slightly different function name for youe swap function such as swap01 or swapThem..etc. Also check your path and set it to current Matlab directory. Regards.

Hi, I am a newbie. How to set path to current Matlab directory ?

"pwd" command gives me C:/Documents/Matlab" . Is it my Matlab directory ? Where shud I set this path ?

From Matlab menu (File), then goto (Set Path) and click on (Add Folder) to add a single directory or (Add with subfolders) to add a folder and its children. You can also type


to reach the same interface.

Don't forget to click (save) after you finish setting your path :)

I notice tat the path is already set to the present directory. But when I run the model, it gives me a Make Error.
