Function Documentation

JGaussianElimination() [1/3]

bool JGaussianElimination	(	const JMatrix &	A,
		const JMatrix &	b,
		JMatrix *	x
	)

JGaussianElimination() [2/3]

bool JGaussianElimination	(	const JMatrix &	A,
		const JVector &	b,
		JVector *	x
	)

Returns true if we were able to perform Gaussian elimination on A|b to reduce A to the identity. The result of b is stored in x.

A does not have to be square. A, b, x must all have the same number of rows. b and x must have the same number of columns.

JGaussianElimination() [3/3]

bool JGaussianElimination	(	JMatrix *	A,
		JMatrix *	x
	)

Returns true if we were able to perform Gaussian elimination on A|x. A and x are both modified. If the process fails, the partial results are returned.

A does not have to be square. A and x must all have the same number of rows.
