This function finds the determinant of the jacobian and deformation matrix (B) of four nodes quadrilateral element in finite element analysis:
function [J_det, B]=Q4(V,r,s)
Input:
V: (4*2) Vertices coordinate matrix. The rows represent each node and columns x-coordinate ,and y-coordinate.
r and s: Values of natural coordinates at the location of integration point.
Output:
J_det: Determinant of the jacobian
B: Deformation Matrix
