Hello, I am trying to create a pyramid matrix, here is what I have so far:

N = input('Enter an odd integer N: ');
if mod(N, 2) == 0
error('N must be an odd integer.');
end

matrix_width = 2 * N - 1;

pyramid_matrix = zeros(N, matrix_width);

for i = 1:N
for j = 1:matrix_width
distance_to_middle = abs(j - (matrix_width+1)/2);
if distance_to_middle == i - 1
pyramid_matrix(i, j) = i;
end
end
end

disp('Pyramid matrix:');
disp(pyramid_matrix);

Here is the result, I am really lost guys, please help me.
