I finally made it work The code actually would be: float (*RegionData)[BLOBDATACOUNT]=malloc(BLOBTOTALCOUNT*BLOBDATACOUNT*sizeof(floa t)); // Blob result array yeppyy, it works :)) -----Original Message----- From: gum...@li...

Subject: Re: [Gumstix-users] C++ & C question Hi its hard to know without seeing the whole thing and I don't really claim to be a programmer! But I think it would be like this: float *Regiondata; Regiondata = malloc(BLOBTOTALCOUNT*BLOBTOTALCOUNT*sizeof(float)); which you would of course have to free() explicitly when you were finished.
