Functions
void	tpt_mat_oprod_q31 (q31_t *aOutMat, const q31_t *aInMatA, const q31_t *aInMatB, uint32_t aM, uint32_t aN)
	Matrix Multiplication of two q31 vevtor.

Detailed Description

The matrix outer product function computes the multiplication of two source vectors and writes the result into a destination matrix. Figure 5 shows the multiplication of vector A by vector B, in which vector A has 3 rows and vector B has 4 columns.

Figure 5. Vector A Multiply Vector B

The outer product can be treated as a matrix multiplication in which source matrices Aij and Bjk have a constraint that the value of j must be 1, as shown below.
