How can I create a matrix which fills each row with an array generated?

The ultimate goal is having the distance_result matrix to be filled with y rows and each row to be filled with x data (array). The first while loop generates the distance_result matrix and the second while loop takes care of the calculations for the distance array.

The problem is that the distance_result matrix has y rows that are all the same. For some reason the distance array is not changing with every iteration. Since y=y+1, then I expect the distance(x) to be changed for every new while loop for y.

Thank you!

clc
clear
x=1;
y=1;
p=1;

while (y<=1000) %y-axis
    while (x<=1000) %x-axis
        distance(x)=5*p*y*x;
        x=x+1;
        p=p+1;
    end
    distance_result(y,:)=distance; %a matrix storing all x-axis and y-axis outputs
    y=y+1;   
end

I think you're not initializing p and x at every new y value. Perhaps you meant this:

y=1;
while (y<=1000) %y-axis
  x=1;
  p=1;
  while (x<=1000) %x-axis
    distance(x)=5*p*y*x;
    x=x+1;
    p=p+1;
  end
  distance_result(y,:)=distance; %a matrix storing all x-axis and y-axis outputs
  y=y+1;
end
fprintf('Done!\n');
imshow(distance_result, []);
axis on;
fontSize = 20;
title('distance_result', 'FontSize', fontSize, 'Interpreter', 'none');
xlabel('X', 'FontSize', fontSize);
ylabel('Y', 'FontSize', fontSize);

set(gcf, 'Units', 'Normalized', 'OuterPosition', [0, 0.05, 1, .95]);

Of course in this case, you should be using a for loop instead of a while loop. Why did you choose to use a while loop???
