How to obtain a value of a function for it's given parameter?

    B1=[0 N1wx mu*N1wy; 0 mu*N1wx N1wy;0 (1-mu)/2*N1wy (1-mu)/2*N1wx]
    B2=[0 N2wx mu*N2wy; 0 mu*N2wx N2wy;0 (1-mu)/2*N2wy (1-mu)/2*N2wx]
    B3=[0 N3wx mu*N3wy; 0 mu*N3wx N3wy;0 (1-mu)/2*N3wy (1-mu)/2*N3wx]
    B4=[0 N4wx mu*N4wy; 0 mu*N4wx N4wy;0 (1-mu)/2*N4wy (1-mu)/2*N4wx]

How can I obtain the value of B1,B2, B3 and B4 which are defined with the value given as shown where N1wx,N1wy and so on are function of xi and eta. I want to obtain the value of B1 for xi=1 and eta=1. How can I perform it?

I think these are shape functions of FEM. What problem you have? Sibstitute the values there simple.
