Hello, could you help me make this code extrude this random profile into the z-axis and make the plot in 3D using mesh or surf?
x = [82,80,65,38,82]
y = [82,54,36,94,82]
plot(x,y)

Ran in:
x = [82, 80, 65, 38, 82];
y = [82, 54, 36, 94, 82];
x = repmat(x, 10, 1);
y = repmat(y, 10, 1);
z = (1:10)';
z = repmat(z, 1, 5);
surf(x, y, z)

Thanks for your help. However, I need the extrusion to be solid (i.e. filled with volume from the inside).

You can't really make it "solid" but you can make it look like it is by closing off the top and bottom so that you can't see inside.
x = [82, 80, 65, 38, 82];
y = [82, 54, 36, 94, 82];
X = repmat(x, 11, 1);
Y = repmat(y, 11, 1);
z = (0:10)';
Z = repmat(z, 1, 5);
surf(X, Y, Z)
patch(x, y, 10*ones(1, 5), 10*ones(1, 5)) % add "lid" on top
patch(x, y, zeros(1, 5), zeros(1, 5)) % add "lid" on bottom
