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。 <*|?x86~ Ue*C>F
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: Wkzs<y" enableservice('AutomationServer', true) w8iR|TV enableservice('AutomationServer') ,Q/Ac{C ~GJN@ka4% 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。 aRJcSV 7\XE,;4> 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: 4 o(bxs" 1. 在FRED脚本编辑界面找到参考. :jEPu3E: 2. 找到Matlab Automation Server Type Library 9 [jTs3l: 3. 将名字改为MLAPP GX&b;N @
