function y = PlaneTrussElementLength(x1,y1,x2,y2)
%PlaneTrussElementLength   This function returns the length of the
%                          plane truss element whose first node has  
%                          coordinates (x1,y1) and second node has  
%                          coordinates (x2,y2).   
y = sqrt((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1));
