How can I creat a "for" that builds more than one matrix?

Basically, I need to creat a Space Truss Member Stiffness Matrix for Member Axes, and every single beam of the truss needs a Stiffness matrix. 'xbar' contain the number of beams in the space truss. The main objective is to get the number of matrix that I need to use the element finite method. But I don't know how to do this at Matlab. I try it earlier this way, but I got the "()-indexing must appear
last in an index
expression. " error.
for i = 1:xbar
rigidlocal(i) = zeros(xbar,xbar);
rigidlocal(i)(1,4) = -1;
rigidlocal(i)(4,1) = rigidlocal(1,4);
rigidlocal(i)(1,1) = 1;
rigidlocal(i)(4,4) = rigidlocal(1,1);
end
