Eli Hughes / CMSIS_DSP_401

V4.0.1 of the ARM CMSIS DSP libraries. Note that arm_bitreversal2.s, arm_cfft_f32.c and arm_rfft_fast_f32.c had to be removed. arm_bitreversal2.s will not assemble with the online tools. So, the fast f32 FFT functions are not yet available. All the other FFT functions are available.

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.

Detailed Description

Tranposes a matrix.

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

Function Documentation

arm_status arm_mat_trans_f32 ( const arm_matrix_instance_f32 *  pSrc,
arm_matrix_instance_f32 *  pDst 
)

Floating-point matrix transpose.

Parameters:
[in]*pSrcpoints to the input matrix
