&U([Wd?E2 简介:
FRED作为COM组件可以实现与Excel、VB、
Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。
oS Ybx:2wo yVK l%GO 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
|S<!'rY enableservice('AutomationServer', true)
U(OkTJxv+ enableservice('AutomationServer')
Fs =)*6}&
\W=Z`w3 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。

在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
;"RyHow 1. 在FRED脚本编辑界面找到参考.
]HXHz(?;F 2. 找到Matlab Automation Server Type Library
+o0yx U
