WebSep 13, 2016 · If you have a routine that takes multiple arguments such as fun (x, y, z), then the pointer construct breaks down as the functions that would call at @fun, such as fzero,have no way of filling in the other arguments. So the declaration construct of '@ (x) fun (x,y,z)' tells Matlab that the variable x is the one to work upon.
