函数help说明，当在command窗口输入help bfilter2时会显示这些说明文字。这些说明文字在m文档中以注释形式出现，在遇到第一个空行（这行什么也么有）或者没有注释的语句结束。

% BFILTER2 Twodimensional bilateral filtering.

%    This function implements 2-D bilateralfiltering using

%    the method outlined in:

%       Gray and Color Images. In Proceedings ofthe IEEE

%       International Conference on ComputerVision, 1998.

%

%    B = bfilter2(A,W,SIGMA) performs 2-Dbilateral filtering

%    for the grayscale or color image A. Ashould be a double

%    precision matrix of size NxMx1 or NxMx3(i.e., grayscale

%    or color images, respectively) withnormalized values in

%    the closed interval [0,1]. The half-size ofthe Gaussian

%    bilateral filter window is defined by W.The standard

%    deviations of the bilateral filter aregiven by SIGMA,
