Ran in:
Don't use globals. Return your variables through the function output. See the documentation. This example from that page shows how to return the variable ave.
myave = average([1:10])
myave = 5.5000
% function declaration
function ave = average(x)
ave = sum(x(:))/numel(x);
end

@Hiroyasu Fujita: how to call functions with one or more outputs is explained here:
https://www.mathworks.com/help/matlab/getting-started-with-matlab.html
Those tutorials explain many basic concepts that you will need to know if you want to use MATLAB.
