How to create these shapes in Matlab

Ive benn trying to complete this assignment with very little luck, here is the code ive managed to write thus far:

filepath1 = '\\myfilepath\\BinaryImage.png';

A = false(100);

figure('Name','Binary images')

subplot(2,2,3) %subplot( no. of rows, no. of cols, position)

for j = 1:100

A(j, 1:(51-j)) = 1;

end

subplot(2,2,3)

imshow(A)

I have attached the question with all the information I have been given.

Any help would be greatly appreciated.

Where is the m-file referenced in the problem statement? That would probably help on some of the coding structure questions. You should initially assign a 2D array of ones to A:

A = ones(100,100);

Then based on which row you are updating you need some "if" statements.So if 1 <= j <= 50, you need to zero out the correct number of columns as a function of j. Then it looks like rows 51 to 75 will have a different outcome, then 76 to 100 and 86 to 100 are all treated differently. So at least four different if/else/elseif statements in your for loop to handle the various shapes you are trying to produce as the index variable j increases.
