Function Documentation

int InvertMatrix	(	double *	InverseData,
		double *	AData,
		int	N
	)

Invert matrix through QR decomposition.

Parameters

InverseData	pointer to memory for holding the result
AData	pointer to column-major matrix data
N	the number of dimensions

Returns

1 on success, 0 on failure

The input data is overwritten during the computation. InverseData should be allocated before calling this function with space for at least N^2 doubles. Matrices are represented in column-major format, meaning A(i,j) = AData[i + N*j], 0 <= i, j < N.
