Ran in:
What function are you trying to call that is giving you the error? The code you shared doesn't use either of the functions you have defined.
The error means you have called a function with more output variables than the function returns. Consider this example.
% Call function with a single output variable
A=f(1)
A = 2
% Your error - call function with more outputs than the function returns
[A,B] = f(1)
Error using solution>f
Too many output arguments.
% function has one output, out
function out = f(in)
out = in+1;
end

Why are you doing this
function [f]=hanu(~,y)
instead of this
function [f]=hanu(y)
That doesn't make sense to me.
Also, what is the line of code where you are calling and what is the complete error message (line number, line of code, error description - everything. ALL THE RED TEXT)?
