Pyramid Table script code

I would like to make a triangle like this one using these source codes that I made already:

function pyramid(a)
for b = 1:a
    base = (sqrt(3)*b)/2;
    height = 1 - (b * 3/2)
    c = [-base base 0 -base];
    d = [height height 1 height];
    plot(c,d); hold on
 end

this only plots the structure of the triangle

how do i make it plot like that? (with inner triangles)

a      = 5;
base   = sqrt(3) / 2;
height = 1 - 3/2;
c      = [-base,  base,   0, -base];
d      = [height, height, 1, height];
figure;
axes('NextPlot', 'add');  % As: hold on
for ia = 1:a
   for ib = 1:ia
      plot(c + (2 * ib - ia) * base, d + 3 * ia * height);
   end
end

I can't seem to squeeze the plot between y = 1 and y = 1 - height, how can i change it that way

I do not understand, what you want. What should be "squeezed"? You can scale the variables base and hight however you like.

[Blake Steven Robers]

The y-axis of the plot should be betwwen 1 and [ 1 - height ]. While its x axis is between [ - base ] and [ + base ]. So the triangle will be just be "squeezed" between those coordinates. Sorry for asking again.

There is no need to say "sorry", because questions about Matlab are the purpose of this forum. Let me mention, that you did not aks a question in your last comment.

According to your description you have to divide the positions by a sacalar factor and shift the y positions by a scalar constant. This is simple maths.
