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
Missing documentation costs end users huge amounts of money and time. Been there, seen that happen.
I'm glad that KEIL/ARM has stepped up and admitted they did not document something. That is rare in a company. Thumbs up. Now go fix the documentation.
Microchip is one of the worst when it comes to documentation.
