MATLAB: Using the while loop function

while loop

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.

MATLAB: For and while loops

function F = getFacWhile(n)
    F=1;
    while n>1
        F=F*n;
        n=n-1;
    end
end
function F = getFacWhile(n)
    F=1;
    for i=1:n
        F=F*i;
    end
end

MATLAB: N doesn’t increase in ‘for loop’

t = zeros(1,10);
t(1:10) = 3

This is what you're doing. You're setting all of the indices (1:100) equal to n. Thus only the last iteration of the for-loop actually matters.

You probably want something like

for n = 1:100
  f(n) = n;
end
