Windows XP and Windows 7

I install matlab on both above tow OS , it works well on XP and not on Windows 7

[debasish]

which version of matlab and windows 7 are you having??

[Jan]

"It does not work" is too vague for a suggestion about how to fix the problem. Please provide any details.

[Mohammed]

I have win 7 ultimate and matlab 2012a

[Mohammed]

I run matlab code , part of the script run fine and the rest I got error msg

*********

[R,P,K] = residue(M.b,M.f);

Attempt to reference field of non-structure array.

Error in rfdemo (line 171)

[R,P,K] = residue(M.b,M.f);

*********

I run the same script on other machine (win xp) and same version of matlab 2012a

the script run OK

[Jan]

Ah, well. This error message means, that M is not a struct. Without seeing the code, it is impossible to guess, what the problem is. But you do have the power to use the debugger to step through your code until you find out, why M is not defined as you expect.

I've had no issue running MATLAB on Windows 7.

[debasish]

nor do anyone out here!!

[Walter Roberson]

debasish, there are a number of documented problems in running earlier versions of MATLAB on Windows 7.

Run Matlab as Admin. (Rightclick ) -- on icon --> Run As Admin

[Mohammed]

I run it as admin, and I get same error

Answer 3

[Jan]

Matlab 2012a is compatible with Windows7 in general.

You hesitate to explain, what "does not work" explicitly means. So I can only guess: When you install the 32-bit Matlab on a 64 bit Windows, the program folder is created in "C:\Program Files (x86)". Some functions will fail due to the spaces in the path. Therefore I've created "C:\ProgramFiles_" in addition and create the 32-bit Matlab there.

dbstop if error

Then run your script. What is M? I am willing to guess it is not a struct and thus why you are getting that error.

This likely has nothing to do with OS.

[Walter Roberson]

It could have to do with different files being on the MATLAB path.
