Detailed Description

void	DSPF_dp_mat_submat_copy (double *restrict x, int rows, int cols, int st, int n, double *restrict y, int dir)

Function Documentation

void DSPF_dp_mat_submat_copy	(	double *restrict	x,
		int	rows,
		int	cols,
		int	st,
		int	n,
		double *restrict	y,
		int	dir
	)

If dir = 0, this function copies n rows starting from st row of matrix x to form matrix y; If dir != 0, this function copies n rows of y to matrix x; The values stored in x and y is double-precision floating values.

Parameters:

	x	Pointer to r1 by c1 input matrix.
	rows	Number of rows in x.
	cols	Number of columns in x.
	st	start index of rows in x to be copied.
	n	Number of rows to be copied.
	y	Pointer to the output matrix.
	dir	data flow direction.

Algorithm:

DSPF_dp_mat_submat_copy_cn.c is the natural C equivalent of the optimized intrinsic C code withoutrestrictions. Note that the intrinsic C code is optimized and restrictions may apply.

Assumptions:

The arrays x and y are stored in distinct arrays. In-place processing is not allowed.

Implementation Notes:

Interruptibility : The code is interruptible.
Endian support : supports both Little and Big endian modes.
