My code has returning issues

function [probcornerstot,probcornersone,probcornerstwo] = xCornersPL(League,Team1,Team2,n)

[~, row1] = ismember({Team1}, League.Team);
[~, row2] = ismember({Team2}, League.Team);

Factor1 = (League.For(row1));
Factor2 = (League.Against(row2));
Team1Corners = Factor1*Factor2*5.2835

Factor3 = (League.Against(row1));
Factor4 = (League.For(row2));
Team2Corners = Factor3*Factor4*5.2825

lambda = Team1Corners + Team2Corners;

probcornerstot = zeros(1,n);
e = 2.7182818284590452;
for k = 1:n+1
    probcornerstot(k) = ((lambda.^(k-1)).*(e.^(-1.*lambda)))./(factorial((k-1)))
end

probcornersone = zeros(1,n);
e = 2.7182818284590452;
for k = 1:n+1
    probcornersone(k) = ((Team1Corners.^(k-1)).*(e.^(-1.*Team1Corners)))./(factorial((k-1)))  
end

probcornerstwo = zeros(1,n);
e = 2.7182818284590452;
for k = 1:n+1
    probcornerstwo(k) = ((Team2Corners.^(k-1)).*(e.^(-1.*Team2Corners)))./(factorial((k-1)))
end

end

Hello! What do I need to change here so that my function only will return the last iteration of ''probcornerstot'', ''probcornersone'' and ''probcornerstwo''? I am also annoyed by the code returning ''ans''. Thank you!

Place semicolons (;) at the end of lines to supress the command window output. Lines that do not end with a semicolon may print output to the command window.

For example,

probcornerstot(k) = ((lambda.^(k-1)).*(e.^(-1.*lambda)))./(factorial((k-1))); 
%                                                               right here  ^

Erik Börgesson's answer moved here as a comment.

Hello and thank you for your answer. When I do that it only returns Team1Corners = x, Team2Corners2 = x, and a matrix of ''ans''. Do you know what more I need to change?

Thank you!

That's because you still have lines that do not end in ;

For example,

Team2Corners = Factor3*Factor4*5.2825   % no ; at the end

As for the "ans" at the end of your code, when your function is done executing at least the 1st output is printed to the command window if the call to that function did not end in a semicolon.

xCornersPL(League,Team1,Team2,n)  % no ; at the end

[addendum]

If all of the outputs are supressed properly, you shouldn't see anything printed to the command window. The output variables will still hold the output data, you just won't see anything printed (unless, of course, you want to see outputs, in which case you'd remove the terminal semicolons).

If you'd like to display the output after the function has completed execution, you can use

disp(VARIABLE)
% Or just 
VARIABLE
