MATLAB: For and while loops

loopsMATLAB

Hi everyone,

How can I write a Matlab function that takes an input integer n and computes the following

n!=n×(n−1)×(n−2)⋯ ×2×1 by using:

The while loop and name it getFacWhile(n).

The for loop and name it getFacFor(n).

Best Answer

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

for index = 1:1:1
    n_value=input('Please, input an n value: \n');
    n=1:1:5;
    manipulate_n=1./(2.^n);
    sum1=sum(manipulate_n);
    fprintf('There are %f n values, the sum is %f, and the difference is %f \n',length(n),sum1,1-sum1)
    n_value2=input('Please, input an n value: \n');
    n2=1:1:10;
    manipulate_n2=1./(2.^n2);
    sum2=sum(manipulate_n2);
    fprintf('There are %f n values, the sum is %f, and the difference is %f \n',length(n2),sum2,1-sum2)
    n_value3=input('Please, input an n value: \n');
    n3=1:1:40;
    manipulate_n3=1./(2.^n3);
    sum3=sum(manipulate_n3);
    fprintf('There are %f n values, the sum is %f, and the difference is %f \n',length(n3),sum3,1-sum3)
end

That was real easy since the for loops only execute one time - basically there's no looping whatsoever.

MATLAB: Convert for loop to while

i = 1 ; 
f = 1 ;
n = 3 ;  
while i<=n
    f=f*i;
    i = i+1 ; 
end
