CMSIS-DSP: Matrix Inverse problem

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...

Why the CMSIS DSP Matrix Multiplication outputs 0 after few iterations?

Hi. I am using the CMSIS DSP library for multiplying two matrices on the keil mcb 1800 board using MCU Xpresso IDE. I am using the external SDRAM of 16 MB for storing the result. Matrix "xmat" is...

CMSIS Matrix inverse returns singular for nonsingular matrices

Hi I have been testing the CMSIS DSP matrix inverse function and am observing unexpected results. In particular, the function arm_mat_inverse_f32 returns ARM_MATH_SINGULAR for matrices that are clearly...
