2D to 3D extrusion

After creating a polyshape from a set of input vertices (x,y) using the polyshape function, I need to extrude and plot the shape (with z value) such that it becomes 3D. Is there any available functions to do that? if not please help me in developing the next lines of code to do so.
The following is the simple way in which I wrote the starting lines of code upto creating a 2D polygon.
clc; clear;
[x y] = ginput(5);
plot(x,y,'r*');
hold on
p1 = polyshape(x,y)
plot(p1)

Here is an example (not tested)
clc; clear;
[x y] = ginput(5);
z0 = 5;
patch(x,y,'r') % face wall
patch(x,y,x*0+z0,'r') % back wall
surface([x(:) x(:)],[y(:) y(:)],[x(:)*0 x(:)*0+z0],'facecolor','r')

No, we can't there are no built-it function for this. BUt you can search at fileexchange
