Hey guys and girls, I'm new to the forum and hoping you can help.

I have a set of 6x6 "matrices" in excel that expand out to give 6
equations each with six unknowns (it is a formula for a composite
lamina that has the 6 known moments and forces in a column on the left
hand side equal to a known 6x6 matrix multiplied by the column of six
unknown strains..hence why each equation gets 6 unknowns). There are no
non-linearites or any other complexities - just the unknowns. It could
be solved linearly or if there is some way of calculating the inverse
of my 6x6 matrix then that would work too.

This would be an easy solution in a program such as MatLab or Mathcad
but i'm completely stuck in excel. Is there some fuction that will let
me solve this... I'm thinking a gauss elimination or something similar
to 2x2 simultanious equations but for 6!

thanks a lot!
Neil
