Cantilever Beam Deflection problem

Hi,

I'm struggling to write a code for the deflection of a cantilever beam using nodes. I want to draw the outline of the beam and show its original shape and the deflected shape over it using nodes. I currently have this code for the basic deflection, but I am having a hard time understanding how I can use this to show the deflection in a more realistic, 2D manner, using nodes. I'm starting over as my previous work was getting messy and convoluted. Any help is really appreciated, just really struggling to get my head around this.

E = 200e9;      % Modulus of Elasticity (N/m^2)
b = 50;         % beam cross section width
l = 150;        % beam cross section height
I = (l*(b.^3))/12   % Second moment of area


x = [0:0.05:1];     % from 0 to max length of 1m
y= 1e6*(((55*x.^3)/3)-((52.25*x.^2)/2))/(E*I);      % Equation for deflection, force = 55kN at 0.95m

plot(x,y);
grid on;
