Hi!
I need a subroutine for VB 6 to invert a matrix,I should use that in a program that solves hyperstatic structures,in other words to solve the system F=K*U (K stiffness matrix).
I read of Gauss-Siedel method that would give me directly U=K^(-1)*F, but I wolud obtain also K^(-1) to check.
In fact now I'm using a subroutine that gives me bad results with 21 x 21 matrix (i checked with mathcad)!
I hope in a help!
Thank you,
Elena
