Develop an Mfile function to compute the factorial using a w

Develop an M-file function to compute the factorial using a while...break loop structure. Your function should check to make sure the input argument is a non-negative integer scalar. Test your function to compute 5! and 9!

Solution

% MATLAB program to calculate factorial

x = input(\'Please enter the number\');

z=1;

If x<0

fprintf(\'This is not a valid input\');

else

while(1)

for y=1:x

z=y*z;

if y==x

break;

end

end

end

fprintf(\'Factorial=%d\',z);

end
