Using an algorithm in matlab:Determine the displacements u_{i} of the joints

enter image description here

The displacement formulation for a plane truss is similar to that of a mass–spring system. The differences are (1) the stiffnesses of the members are k_{i} = (EA/L)_{i}, where E is the modulus of elasticity, A represents the cross-sectional area, and L is the length of the member; (2) there are two components of displacement ateach joint. For the statically indeterminate truss shown, the displacement formulation yields the symmetric equations Ku = p, where

Could someone help me with the algorithm?

Thanks for your help

You should use the backslash operator. Type help slash for more information. Basically, 

u = K\p

means u = inv(K)*p but is a faster more accurate way to do it. I haven't tested it for your problem, but this is generally how to go about these sorts of problems.
