matlab2015a支持的usb webcams support package

由于MATLAB2015a安装的是免费版，在用videoinput时便出现问题如下：

 

01. imaqhwinfo
02. 警告: No Image Acquisition adaptors found. Image acquisition adaptors may be available as downloadable support packages. Open Support
03. Package Installer to install additional vendors.
04.
05. ans =
06.
07. InstalledAdaptors: {}
08. M<a href="http://www.it165.net/pro/" target="_blank" class="keylink">ATL</a>ABVersion: '8.3 (R2014a)'
09. ToolboxName: 'Image Acquisition Toolbox'
10. ToolboxVersion: '4.7 (R2014a)'

于是安装webcam来解决读取摄像头问题：

 

点击:Get Hardware Support Packages

出现以上的界面，点击USB Webcams 安装。
