I am a newbie, very newbie in MATLAB.

I am trying to solve a set of equations that looks like this...

[Pxa Pya 0 0 0]' = [constants]*[0 0 Ua Va Mza]'

I need to solve Pxa, Pya, Ua, Va and Mza...
What shall I do to solve them.

So presumably [constants] is a 5 by 5 array of known constants. And
you have unknowns on both sides of your equation. Strange.

Well anyway, here's one answer for you (of which I think there could
be an infinite number more):
They're all zero.
How's that for a solution? It works!
Now, do you want to explain what you really want to do? Is this some
kind of least squares situation you're trying to formulate?

I am trying to solve for displacements of a certain structure using matrix structural analysis.
