backsub:

Syntax:	backsub ( LIST, B )

Description:

	The backsub function computes the solution to the set of
	linear equations described by:

		A * X = B

	The 1st argument to backsub (LIST) is the result from
	`factor(A)'. The second argument to backsub is the matrix B. B
	can contain multiple right hand sides.

	Backsub returns a matrix X which contains the solution(s) to
	the aforementioned equations.

	Backsub utilizes the LAPACK subroutines DGETRS or ZGETRS.

	Example:	X = backsub (factor (A), B);
