Why can't it proceed to the next iteration of for 'runs' loop?

nruns = 10; nphoton = 100; m = nphoton;
for runs = 1:nruns
q(:,runs) = rand(nphoton,1);
while m > 0
for i = 1:nphoton
s(i,runs) = 2*pi*q(i,runs);
m = m - 1;
end
end
end
Why array of s only save the first iteration of runs == 1? I can't solve this problem, too much loops. Please help..

mrbond99 - please look at the condition for the while loop
while m > 0
You will only enter this loop so long as m is positive...but the body of this loop decrements this variable on each iteration of the for loop. Since it is never reset to nphoton, then this code will never be executed again. I think that you want to move the decrement to this variable outside of the for loop.
for runs = 1:nruns
q(:,runs) = rand(nphoton,1);
while m > 0
for i = 1:nphoton
s(i,runs) = 2*pi*q(i,runs);
end
m = m - 1;
end
end
Or can you remove the m altogether and reduce the code to simply
for runs = 1:nruns
q(:,runs) = rand(nphoton,1);
for i = 1:nphoton
s(i,runs) = 2*pi*q(i,runs);
end
end
? Is the m necessary?
