efg 1d program

Dear Prof. Dolbow

 In your 1D efg program, you have used u=d(1:nnodes). I think, you should calculate "u" by summing after multiplying with the shape functions and "d". Because in the figure 2 phi(x) is not equal to one at the node. Phi(x) satisfies the partition of unity.

Please clearify my doubt if I am wrong.

Best regards
