Matrix Initialization

Functions
void	arm_mat_init_f32 (arm_matrix_instance_f32 *S, uint16_t nRows, uint16_t nColumns, float32_t *pData)
	Floating-point matrix initialization.
void	arm_mat_init_q15 (arm_matrix_instance_q15 *S, uint16_t nRows, uint16_t nColumns, q15_t *pData)
	Q15 matrix initialization.
void	arm_mat_init_q31 (arm_matrix_instance_q31 *S, uint16_t nRows, uint16_t nColumns, q31_t *pData)
	Q31 matrix initialization.

Description

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