comsol script compatibility 32 toward 64 Bits

a file (comsol with matlab with a graphical interface ) running perfectly in 32 bits yield the following error message

??? Error using ==> flgetsparse
Function "mxGetIr_700" is obsolete in file ".\compat32.cpp", line 264.
(64-bit mex files using sparse matrices must be rebuilt with the "-largeArrayDims" option.
See the R2006b release notes for more details.)

do i have to recompile the matlab file code source C with the mex function and a compiler ?
especially, which files where?

since i have the last version of matlab (R2010a) i believe that the 64 bits represention of array was activated by deffaut, do i have to change some stuff in my m file only?

thank you for any help from peoples who have already encountered this problem

Does anyone have a solution for this?

I have the same problem when applying the assemble() function. It worked well with Matlab R2008a (64-bit), but not with R2010a.

Hi

I would say that is worth to report directly to support too.

Anything new on this, because I can't figure this out? I am trying to export comsol model to simulink without success with Comsol 3.5a and Matlab 2010b.

BG,

Jyri

I have the same problem.

I am using Matlab R2010b 64bit and Comsol 3.5a 64bit on Win7 64bit.
The script was written and executed using Matlab R2009b 32bit with Comsol 3.5a 32bit on WinXP 32bit.

It appears to me at a first glance that there is some MEX-files in Comsol that use coding incompatible to large array handling with 64bit. Therefore, the used MEX-files would need to be updated in order to work properly with 64bit.

Source: www.mathworks.com/support/solutions/en/data/1-5C27B9/?solution=1-5C27B9

So I have the impression that I need to fix files of the 64bit Comsol installation to make it work with 64bit and matlab. Shouldn't the people that get paid for the product fix it?

Best regards
Daniel

Hi

are you sure v3.5a was made compatible with a matlab 2010b ?
I would have expecteds a 2007 or 2008 at most, matlab has changed quite alot the last years too

Hi Ivar

There is a hotfix for Comsol 3.5a to support MATLAB 2008b or 2009a:
www.comsol.com/support/updates/comsol35a1/

In order to use Comsol 3.5a with MATLAB 2009b or 2010a an additional patch is necessary:
www.comsol.com/support/updates/comsol35a3/

However, for me it solved the problem to downgrade from MATLAB 2010b (64bit) to MATLAB 2009b (64bit) without having the hotfix or the patch installed.

Best

I used the 64 bit win 7, 64 bit comsol 3.5a, 64 bit 2010a matlab,
I have the same problem
