Why is my if statement making the values of a previous array disappear?

My code basically looks like:
for x = 1:xmax
for y = 1:ymax
for l = 1:xmax
for m = 1:ymax
d(x,y,l,m) = (x-l)^2 + (y-m)^2
if f(x,y,1) ~=f(x,y,5)
%lots of new defined values
else
break
end
end
end
end
end
There is no problem when I remove the if statement, I get the correct array for d. But when the if statement is there the output of d is all zeros. Does anyone know why d is not calculated when I have the conditional in there since it's outside of the if?

break will terminate your for loop, and it won't continue all the way to ymax.
Perhaps you mean you use continue? Or just leave the else case out altogether?

How would the f array ever change? And, have you tried stepping through the code with the debugger? That's what I do, and everyone else would do. Try this: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/
