sparse linear system solver
x=lusolve(hand,b) x=lusolve(A,b)
full real matrix
real square sparse invertible matrix
handle to a previously computed sparse lu factors (output of lufact)
full real matrix
x=lusolve(hand,b)
solves the sparse linear system
A*x = b
.
[hand,rk]=lufact(A)
is the output of lufact.
x=lusolve(A,b)
solves the sparse linear system
A*x = b
