Why do I receive "Machine_Problem_8" requires more input arguments to run?

% longestword.m

function out = Machine_Problem_8(Heat, Lakers, Warriors)

% Matlab function that takes as inputs 3 words and return the word with

% the most number of characters (and the first in the list when they

% have the same length)

% set out to word1

out = Heat;

% strlength is used to return the number of characters in input string

% if number of characters in word2 > out, set out to word2

if(strlength(Lakers) > strlength(out))

out = Lakers;

end

% if number of characters in word3 > out, set out to word3

if(strlength(Warriors) > strlength(out))

out = Warriors;

end

end

%end of longestword.m

How did you call your function? You can't just press the "Run" button in the editor to call a function that expects input arguments.

Also, Matlab expects the filename of a function mfile to match the name of the first function in the file, so either rename the longestword.m file to Machine_Problem_8.m or change the function name to longestword (I would recommend the latter).

I would also recommend using generic names inside the function. In other words, replace Heat with word1, etc. Then you would call the function like this at the command line: longestword("Heat", "Lakers", "Warriors").
