MATLAB: How to define functon Unit sample sequence

Question

function [x,n]=edinecenImpuls(n0,n1,n2)

I can't define this function in MATLAB It says " Use of brackets [] is unnecessary. Use parentheses to group, if needed."

I don't know what is wrong please help

Answer 1

function [x,n]=edinecenImpuls(n0,n1,n2) 
n=n1:n2; 
x=(n-n0)==0;
