Comments on: Undocumented Matlab MEX API

Correct signatures for these two functions are:

extern mxArray* mxGetPropertyShared( mxArray const* pa, mwIndex index, char const* propname );
extern void mxSetPropertyShared( mxArray* pa, mwIndex index, char const* propname, mxArray const* value );

(Note that mwIndex has a different basic type depending on the architecture.) Noteworthy is that the MATLAB code for the property setter and getter methods will be executed here, so these functions are not necessarily quick. It is sad that we cannot create class methods as MEX-files.

Interesting news from the R2015a release notes: mxCreateUninitNumericMatrix and mxCreateUninitNumericArray are now *documented* functions.

In reply to Ilan Bar.

@Ilan – I don’t have access to Linux at the moment so I’m afraid someone else would need to answer this…

Yair,
mxGetPropertyShared is working great on Windows. Do you know whether there is a way to use it on LINUX as well ? The generic solution solution by James Tursa works consisting of mxGetPropertyPtr works for LINUX but slows processing speed if called many times.

Best Regards,
Ilan.

Would you open a Google+ Page?
It will make following you much easier.

Thanks.

Thank you. Very interesting. I don’t know why some of these aren’t documented. However, mxIsInf is documented: http://www.mathworks.com/help/matlab/apiref/mxisinf.html
