MATLAB: How to plot three dimensional triangular based pyramid

3d pyramid3d shapes

I want to plot a 3d triangular based pyramid in Matlab. In 2d it's basically an equilateral triangle. Shall I need to write an equation for each faces individually?
How can I plot it?
Thanks in advance.

Here is the way
[x,y] = pol2cart(deg2rad(0:120:360),1);
x1 = [x*0; x; x*0];
y1 = [y*0; y; y*0];
z1 = [x*0+1; x*0; x*0];
surf(x1,y1,z1)
