I'm trying to learn some DSP on the Teensy LC so it would be super nice if this could be fixed somehow.

Any reason why arm_math.h is hard coded for CORTEX_M4?

Thank you for your work on Teensy. Very much appreciated!

Hi Paul, is this the currently used version? I'd like to compile it with a newer GCC.

Hello,
I have an algorithm using arm_math_inverse.
In one operation I reuse the input operand passed to arm_mat_inverse.

arm_mat_inverse(&SumCk, &InvSumCk); // SumCk value changes in the inverse operation
arm_mat_mult(&SumCk, &Dk, &result); // Bad result because SumCk doesn't have his original value

arm_status arm_mat_inverse_f32(const arm_matrix_instance_f32 * pSrc, arm_matrix_instance_f32 * pDst)
The pSrc parameter is declared as const. The pSrc value never would change.

The algorithm performs a sequence of elementary row operations till it reduces the input matrix to an identity matrix.
The input matrix changes.

Is there any other arm_mat_ function that changes the input parameters?
Thank you
