## Functions

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

## Description

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

Transpose of a 3 x 3 matrix

## Function Documentation

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

Parameters

  [in] | *pSrc | points to the input matrix
  [out] | *pDst | points to the output matrix

Returns
  The function returns either `ARM_MATH_SIZE_MISMATCH` or `ARM_MATH_SUCCESS` based on the outcome of size checking.
