for loop n*n matrix with a given formula

I want to write a code for the following problem:

The code must be able to determine the head (h) at every x and y. I have constructed the formula, and now I want to construct a n*n matrix for every head at every position with a for loop. I have constructed the following:

%%Example 7.1

A=(-4/500);
B=(-2/300);
C=120;

x=-100:10:600;
y=-600:10:100;

h=zeros(71);
for i=1:71
    h(i,:)=A*x(i)+B*y(71)+C;
    h(:,i)=A*x(1)+B*y(72-i)+C;
end

Thanks in advance.

@Lodewijk Pleij: what is your question?

I assume your looking for something like this, so you'll end up with a matrix h with size 71x71 (rows = x, columns = y)

clear all;
close all;

A = (-4/500);
B = (-2/300);
C = 120;

x = -100:10:600;
y = -600:10:100; 

n = size(x,2);
h = zeros(n);

for i = 1:n
    for j = 1:n
        h(i,j) = A*x(i) + B*y(j) + C;
    end
end
