matlab a function in m-file

akira32

我??在bb.m宣告一??function叫improd,可是?我?绦
>> f=[1 2 ; 3 4];
>> g=[1 2 ; 2 1];
>> improd(f,g);
??? Undefined command/function 'improd'.


% in bb.m file
function [ p, pmax, pmin ,pn ] = improd ( f, g )
% help22
fd=double (f);
gd=double (g);
p=fd.*gd;
pmax=max(p();
pmin=min(p(:));
pn = mat2gray(p);


?为??绦
>> bb
??? Input argument "f" is undefined.

Error in ==> bb at 3
fd=double (f);

我有??疑??就算我在m-file的function定?都??matlab怎?知道目前我呼叫的function是定?哪一??m-file,??烧呤侨绾侮P?的?
