CMSIS-DSP: Matrix Inverse problem

kaveh firouzi

Hello,

While debugging a DSP algorithm, I realized the problem is duo to the CMSIS matrix inverse function: arm_mat_inverse_f32. It's really strange and is driving me crazy. arm_mat_inverse_f32 returns the right result for some Matrices but wrong result for some other! I assure you the matrices are not singular or anything like this, the algorithm works just fine with the same input data on MATLAB. I have no idea what the problem could be, any suggestions?

Regards

    A stupid mistake by me! sorry for the waste of time.

    It would be less of a waste if you told what that mistake actually was. As-is, nobody but you learned anything from this exercise, so it would be quite an improvement if future readers were to find a "Don't do ...this..., because it won't work" kind of lesson in this place.
