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.
