I'm trying to learn MATLAB now; I tried a simple step, factorial function.

factorial.m:

function result = factorial (m)
    if m == 1
        result = m;
    else
       result = m .* factorial(m.-1);
    end

and then call it like this:

x = 2;
f = factorial (x)

but all I get is an error:

Missing variable or function.

1. You have a syntax error, in the second line there shouldn't be a . after the 2nd m
2. The if should be in a separate line from the function declaration.
