Functions

arm_status arm_mat_trans_f32 (const arm_matrix_instance_f32 *pSrc, arm_matrix_instance_f32 *pDst)
 Floating-point matrix transpose.
 
arm_status arm_mat_trans_q15 (const arm_matrix_instance_q15 *pSrc, arm_matrix_instance_q15 *pDst)
 Q15 matrix transpose.
 
arm_status arm_mat_trans_q31 (const arm_matrix_instance_q31 *pSrc, arm_matrix_instance_q31 *pDst)
 Q31 matrix transpose.
 

Description

Tranposes a matrix. Transposing an M x N matrix flips it around the center diagonal and results in an N x M matrix.
