MATLAB：Psychtoolbox安装

由于需要在Matlab上安装Psychtoolbox，我先去查找了一些相关的经验贴，然后按照如下操作进行安装的。

1.下载DownloadPsychtoolbox.m

这里我找到了Psychtoolbox的官方安装网址：http://psychtoolbox.org/download#download-problems

下载对应的Psychtoolbox.zip文件，然后打开matlab，运行第二步

2.运行命令

把路径切换到你保存DownloadPsychtoolbox.m文件的地方，在命令行里输入

>>DownloadPsychtoolbox('此处填写安装DownloadPsychtoolbox.m的路径')

运行后显示如下：

DownloadPsychtoolbox(‘E:\matlab’)
DownloadPsychtoolbox(‘E:\matlab’,‘beta’,’’, 0)

Requested location for the Psychtoolbox folder is inside: E:\matlab
Using optimal client for subversion checkout.

Downloading via Matlabs integrated SVNKit: This can take multiple minutes.
There may be no output to this window to indicate progress until the download is complete.
Please be patient …
Download of SVN revision 12166 succeeded!
Now adding the new Psychtoolbox folder (and all its subfolders) to your MATLAB / OCTAVE path.
Success.
Now setting permissions to allow everyone to write to the Psychtoolbox folder. This will allow future updates by every user on this machine without requiring administrator privileges.
