UC知道matlab 调用函数

帮忙看看是什么问题，急死了的
function[p,pmax,pmin,pn]=Z(f,g)
%IMPROD Computes the produce of two images.
%[P,PMAX,PMIN,PN]=IMPROD(F,G) outputs the element-by-element
%product of two input images,F and G,the product
%maximum and minimum values,and a normalized product array with
%values in the rang[0,1].The input images must be of the same
%size.They can be of class uint8,uint16,or double. The outputs
%are of class double.
fd=double(f);
gd=double(g);
p=fd.*gd;
pmax=max(p(:));
pmin=min(p(:));
pn=mat2gray(p);
之后，我定义了一个
>> f=[1 2;3 4];
>> g=[1 2;2 1];
运行
>> [p,pmax,pmin,pn]=improd(f,g)
出的提示??? Undefined command/function 'improd'.
是怎么回事？

函数名……
function[p,pmax,pmin,pn]=improd(f,g)
%这里：你命名函数为Z，却调用improd肯定不行……

最后，要把这个文件命名为improd.m (和函数名相同)
这样才可以用improd调用
