MATLAB Function Syntax

Question

Now I'm trying to learn MATLAB ; 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 error:

Missing variable or function.

Answer 1

• You have a syntax error, should not be in the second line . after the second m
• if should be on a separate line from the function declaration.

Answer 2

You need one more "end": the first ends the if statement.

Answer 3

You are an end or if-else statement, but not an end function. Add an extra end to the end.

Answer 4

if m == 1;

you forgot ";"
