draw min squares in black and white

Hi every

I want to plot min squares in black and white like the attachment

I had an idea (I didn't try it that i make the 3-dim image matrices)

Is there other solutions???

What are "min squares"? Why do you need Matlab to do this?

[Ahmed raafat]

I mean with like a grid with square size 1cm*1cm

And it is a task

Please see the attachment to understand me of min squares

Do the following:

   m = 16; n = 33;
   A = false(m,n);
   A(1,17) = true;
   for k = 2:m
     v = 2:n-1;
     A(k,v) = A(k-1,v-1)~=(A(k-1,v)|A(k-1,v+1));
   end

Then use the A(:,2:n-1) matrix to determine which squares are to be black (true) and which are white (false.) I’ll leave the plotting up to you.

Thanks mr.Roger

It worked

It should be noted here that your “rule 30” presumably refers to a logic method devised by Stephen Wolfram for generating a pseudo-random sequence of binary digits. The “30” refers to the binary representation of the truth table involved: 00011110.

Seems like homework, so here's a hint. Look at the pattern. The three binary squares above are 7, 6, 5, 4, 3, 2, 1, 0. You just need to turn the three elements above the current element into a decimal number like

decNumber = 4*A(row-1, col-1) + 2*A(row-1, col) + A(row-1, col+1);

Then if decNumber is 1 through 4 inclusive, then set the value to 1, otherwise it's zero.
