Detailed Description

Implementation of the matrix inversion.

The function in INVERT.H compute a matrix inversion with a LUP method

Function Documentation

opj_matrix_inversion_f()

OPJ_BOOL opj_matrix_inversion_f	(	OPJ_FLOAT32 *	pSrcMatrix,
		OPJ_FLOAT32 *	pDestMatrix,
		OPJ_UINT32	nb_compo
	)

Calculates a n x n double matrix inversion with a LUP method.

Data is aligned, rows after rows (or columns after columns). The function does not take ownership of any memory block, data must be fred by the user.

Parameters

pSrcMatrix	the matrix to invert.
pDestMatrix	data to store the inverted matrix.
nb_compo	size of the matrix

Returns

OPJ_TRUE if the inversion is successful, OPJ_FALSE if the matrix is singular.

Calculates a n x n double matrix inversion with a LUP method.
