This is a dedicated mex-file for use with UMFPACK to efficiently complete the permuted forward/back substitution to solve linear systems, A*x = b when A is sparse and b is a dense vector.
UMFPACK is used when the MATLAB function "lu" is called with 4 outputs:
[L, U, P, Q] = lu(A, tol);
The mex-file provides the solution:
x = LUsubs(L, U, P, Q, b);
and generally results in a CPU time saving of a factor of 3-4 (On my machine).
Type "LUdemo" and "help LUsubs" for more information.
A pre-compiled version is included. If you have the MATLAB compiler you can re-compile the file via:
mex -O LUsubs. c
You will need either windows or the compiler to use this function.
Demands:
• MATLAB Release: R13
