using the while loop function

I am new to MATLAB and trying to use a while function and not understanding why there is no error, but keeps the system busy with no result.

function fac=fact(n);
fac=1;
while n>0
  fac=fac*n;
  n-1;
end

You're close!

Inside the loop you say:

n-1

This just does the computation but does not assign this value back to n. You want:

n = n-1;

Which will reduce the value of n.

Thank you, it was racking my brain why it looked why it would work but didn't.

Hi, Inside the loop you should use n = n-1, it should solve your problem.
