%%file y.m
% Define the function
function [ y ] = x( n )
if n < 0 | n >= 10
y = 0;
else
y = 5;
end
end
it turns back with Error in y (line 4)
if n < 0 | n >= 10
this is literally copied by my lecturers instructuons.

If you call your function like this:
y = x()
what value should MATLAB use in the if statement condition where it tries to validate the value of n?
if n < 0 | n >= 10
You need to tell the x function what n is, like:
y = x(5)

what if I wanna introduce n as a vector like n = -15:18;?

Is that related to the not enough input arguments error? Kind regards
