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

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.

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

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.
