Undefined function 'geoidtst' Error

Hi

I use Azimuth function in my project. It worked very good until this afternoon. Now, I try to run my script and I receive an error message as below:

'Undefined function 'geoidtst' for input arguments of type 'double'.'

Does every body know how I can solve this problem?

Thanks a lot

Mani

Which version of Matlab are you running on each machine? And do you have the Mapping Toolbox installed on both? What does

which azimuth -all

return on each machine?

The geoidtst function was part of earlier versions of the Mapping Toolbox (it's present in the old Matlab74 copy I have), but a lot of helper functions related to reference ellipsoids and geoids and the like have been changed since then. Are you perhaps trying to use an old copy of azimuth.m with a newer copy of Matlab?

[Rob Comer]

Kelly's guess that you may be trying to use an old copy of azimuth.m makes sense. The geoidtst function was on the MATLAB path, but never documented, through R2011b. It was used internally to validate "geoid vector" inputs. It was removed in R2012a, the same release in which reference spheroid classes were introduced. (For backward compatibility, it's still possible to use "geoid vectors", but the internal validation no longer uses geoidtst.)

Most likely, the geoidtst function is in some folder that Matlab can't find. You can change directories to that folder, or use the addpath function to add that folder as a path where Matlab will look for geoidtst. If you can't find geoidtst, this looks like it.

Matlab will look in any path you add, until you restart Matlab. It's possible that last time when your script worked, Matlab knew to look in the right path, but as soon as Matlab closes, it forgets where to look.

I tried it but problem doesn't solve. I used command 'restoredefaultpath; matlabrc' to reset path of MATLAB,too. but nothing changed.

As I remember, I added new path through 'Set path' menu, but I never remove default paths in dialogue. After that my problem accures and kills my time!

Please help me to solve pitfall.

Thanks

Matlab simply can't find geoidtst. Create a file in your home folder, and call it startup.m. In that file include a line like this

addpath('filepath/ToFolder/ContainingGeoidtst')

where of course you'd have to change the file path to the actual file path you're using. Matlab will automatically add this path to the directory every time you start Matlab.

Type this into the command window

which -all geoidtst

Also, what toolbox is it in? You forgot to list it in the Products box above. Whatever it is, do you have a license for it? Type ver to find out. What does it say when you type which and ver?

[Mani Ahmadian]

I run above command on a healthy machine and I receive this message:

>> which -all geoidtst

'geoidtst' not found.

My script runs on this machine perfectly and without this function!!!

Why it is possible?! I do not understand what happens in two machines!

Does anyone explain it for me, please?

Evidently when you ran it on the "healthy machine" the program flow never got to where it was calling geoidtst. Set a breakpoint there and you'll see it never stops, because if it did, and the function was not on that machine, it would throw an error.

By the way, are you ever going to list above what Product/toolbox this function is in?

[Iain]

Its in the mapping toolbox.

Thanks - I added above.
