1) Create a function file called myfunction.m in your working directory. E.g.,
edit myfunction.m
2) Put the following code into this file:
function result = myfunction(n)
% Insert your n check code here
result = 0; % initialize the result
% Insert a loop here to add the terms to result
return
end
Insert your code for n checking and term adding into the places indicated. Also add comments to this file to state the purpose of the function, show the calling syntax, and explain what the inputs and outputs are.

The 'while' statement example in the following link is a good starting point - https://www.mathworks.com/help/matlab/matlab_prog/loop-control-statements.html
