老大，我需要端点检测程序啊，着急用啊，看到了千万与我联系，好吗？
我ＱＱ：２４０３８３６８０
麻烦一下
老大，我把这段程序拷到 MATLAB里也不能运行呀，为啥呀，提示我：??? Undefined command/function 'enframe'.
Error in ==> vad at 23
tmp1= enframe(x(1:end-1), FrameLen, FrameInc); 谁能帮帮忙，怎么改一下可以运行，我的是matlab7.0

看看版规，注意用词。那个应该是个子函数，主任没有贴出来想必是在另外的地方可以找到的。 不好意思啊，我刚来论坛的，不太清楚规矩。
我找了好多地方，整个论坛，包括网上其他地方也都找了，但是都是这段程序，我刚接触MATLAB，不知道怎么改，可以指点一下么，需要加点什么才能看到运行结果? 有可能发的时候遗漏了这个函数 这里给出enframe函数:
function f=enframe(x,win,inc)
%ENFRAME split signal up into (overlapping) frames: one per row. F=(X,WIN,INC)
%
% F = ENFRAME(X,LEN) splits the vector X up into
% frames. Each frame is of length LEN and occupies
% one row of the output matrix. The last few frames of X
% will be ignored if its length is not divisible by LEN.
% It is an error if X is shorter than LEN.
%
% F = ENFRAME(X,LEN,INC) has frames beginning at increments of INC
% The centre of frame I is X((I-1)*INC+(LEN+1)/2) for I=1,2,...
% The number of frames is fix((length(X)-LEN+INC)/INC)
%
% F = ENFRAME(X,WINDOW) or ENFRAME(X,WINDOW,INC) multiplies
% each frame by WINDOW(:)

这个论坛挺好，速度快，人也都不错:victory: :victory: :victory:
