## Functions
void | arm_mat_init_f32 (arm_matrix_instance_f32 *S, uint16_t nRows, uint16_t nColumns, float32_t *pData)
void | arm_mat_init_q31 (arm_matrix_instance_q31 *S, uint16_t nRows, uint16_t nColumns, q31_t *pData)
void | arm_mat_init_q15 (arm_matrix_instance_q15 *S, uint16_t nRows, uint16_t nColumns, q15_t *pData)

## Detailed Description

Initializes the underlying matrix data structure. The functions set the `numRows`, `numCols`, and `pData` fields of the matrix data structure.
