Hi everybody,

I have problem with this function below. Please help me!!!

Code:

%keySet and valueSet is input
keySet = {'Jan','Feb','Mar','Apr'};
valueSet = [327.2 368.2 197.6 178.4];
function [output] = Dosomething(keySet,valueSet)
    M = containers.Map(keySet,valueSet);
    % In this function, how to access element of M when I don't know 'keySet' value?
    if M('Jan') == 327.2
        disp('correct')
    end
end

I mean, when I make this function, I'm going to pass non-fixed arguments into this function, so how do I pass in a function that can map the pairs of parameters to each other so that I can utilize them?

Thanks and Best Regards,

Kiet Vo
