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?
