Hi, I am very new to matlab and need some basic help.
function classifier = learnknn(k, d, m, Xtrain, Ytrain)
classifier = {k, d, m, Xtrain, Ytrain};
end
I get the error " Not enough input arguments. "
But, I cannot change the first line of this code. Only the body of the function can be modified.
Thank you.

Thank you Walter.
so if I understand,
function classifier = learnknn(k, d, m, Xtrain, Ytrain)
is actually all I need? no
end
keyword?
and what if I wanted the classifier function to return a diferent datastructure than a cell?
for example, if I wanted to return a list object containing the input objects.
Thankyou.

No, the syntax that Walter Roberson showed replaces your entire function. It uses the special varargin variable:

"and what if I wanted the classifier function to return a diferent datastructure than a cell? for example, if I wanted to return a list object containing the input objects."
MATLAB does not have a "list" type:
