matlab编程实现有限元计算,对有限元学习很有帮助

function y = BeamElementShearDiagram(f, L)
%BeamElementShearDiagram   This function plots the shear force 
%                          diagram for the beam element with nodal
%                          force vector f and length L.
x = [0 ; L];
z = [f(1) ; -f(3)];
hold on;

plot(x,z);
y1 = [0 ; 0];
plot(x,y1,'k')
