36 @brief Implementation of the matrix inversion
38 The function in INVERT.H compute a matrix inversion with a LUP method
41 /** @defgroup INVERT INVERT - Implementation of a matrix inversion */
43 /** @name Exported functions */
45 /* ----------------------------------------------------------------------- */
48 * Calculates a n x n double matrix inversion with a LUP method. Data is aligned, rows after rows (or columns after columns).
49 * The function does not take ownership of any memory block, data must be fred by the user.
51 * @param pSrcMatrix the matrix to invert.
52 * @param pDestMatrix data to store the inverted matrix.
53 * @param n size of the matrix
54 * @return OPJ_TRUE if the inversion is successful, OPJ_FALSE if the matrix is singular.
