For loop within a function?

How can I put a for loop inside of a function? I'm trying to get the factorial of an input. Any given input.

Like if I pull up the function an put any number inside, to have its factorial be the output.

A function is like any other script file, except it is saved as a function.

For example, to get the sum of the elements of a vector, this is one option using a for loop inside a function:

function p = vector_sum(x)
p = 0;
for k1 = 1:length(x)
    p = p + x(k1);
end
end

Then call it as:

z = 1:10;
sum_from_1_to_10 = vector_sum(z)

You can adapt this idea to calculate the factorial for your assignment.

See the documentation for Function Basics for details.

I don't understand why do you going for for loop instead of using the inbuilt factorial function

   n = 3;%input value
  f = factorial(n)

It's part of hw assignment

[Stalin Samuel]

function f = fact(n)
f = 1;
for itr = 2:n
    f = f*itr;       
end
end

save the above code as separate file in your working directory and from main file use the below code to call the function

   n = 3;%input value
  f = fact(n)
