我完全按顶楼的安装步骤进行了安装，且是下载的楼主的文件，在运行时为什么还是出现以下错误啊？（与用网站上下载的文件的错误还是一样），请哪位大哥帮帮忙！

Beginning the UCSD_GARCH demo program.  This program is designed to
help you get a basic feel for the programs included, but does not show all
functionality.  Please press a key to continue.

We will begin by simulatig a simple univariate GARCH process with normal innovations.
The command to do this is:

[x,h]=garchsimulate([.01; .2; .75],1,1,1000)

where x is the output data series, h is the output conditional variances, the vector [.01; .04; .94]
represents the constant, arch and garch parameters, the two 1s represent the arch and garch orders.
and 500 is the amount of output desired.

??? Undefined command/function 'garchsimulate'.

Error in ==> ucsd_garch_demo at 23
[x,h]=garchsimulate(1000,[.01 .2 .75]',1,1);

太贵了。下面James P.LeSage的内容对我们穷人是有用的，其主页为：

安装的说明：（见其Introduction）

To obtain, install and use these functions:

• Go to the download index item at the left
• Download the zip file
• unpack the zip file to a folder of your choice
• Start MATLAB and use the file/menu/set path item
• On the set path dialogue choose add folder with sub-folder
• Use the file navigation window to select the root folder where you unpacked the toolbox functions
• Use the Save and Close to exit the set path dialogue window

DO NOT try downloading individual files using the view menu item. This will not give you a working function because almost all of these functions call other functions in the toolbox, so you need the whole thing.

同时有两本计量的免费的PDF，相关数据。

俺尊重LZ的贡献，同时也给咱穷人一点帮助。

安装好像挺简单啊  matlab里面 set path就行啊

怎么还要收费？

怎么安装啊？还是不行！
