I'm trying to create this function, and I am getting an error. I don't know what I am doing wrong...
>> function [y] = myfunc( x, y, z )
y = -9*x - 10*y+ z*(-log(100-x-y)-log(x)-log(y)-log(50-x+y));
end
function [y] = myfunc( x, y, z )
↑

Only anonymous functions may be defined in the command window:
>> fun = @(x,y,z)-9*x - 10*y+ z*(-log(100-x-y)-log(x)-log(y)-log(50-x+y));
>> fun(1,2,3)
ans =
-56.599051375363
Other function types (those defined using the keyword function) must be defined in an Mfile.

I guess you have copied this under some already existing code. Copy this in fresh m file and save.
