{[Y7h}7 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。
=h|cs{eT\2 5/h-Hr 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:
G{>PYLxOb enableservice('AutomationServer', true)
.sM,U enableservice('AutomationServer')
FeO1%#2<y
J-uQF| 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。

l@F mEi(DW)( 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:
-{9mctt/gE 1. 在FRED脚本编辑界面找到参考.
=>evkaj 2. 找到Matlab Automation Server Type Library
RjO0*$>h 3. 将名字改为MLAPP
