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。 k,'M mAz c;]^aaQ+> 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： !mWm@ }Ujg enableservice('AutomationServer', true) 9bRUN< enableservice('AutomationServer') \(=xc2  |7n%8JsY!" 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。 vg3iT } A /c
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： 7!(/7U6rP 1. 在FRED脚本编辑界面找到参考. 3?`TEw~' 2. 找到Matlab Automation Server Type Library :/6aBM ? 3. 将名字改为MLAPP N}[!QE 3G 5xIr6
K0o${%'@7 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 GV ) "[O =_3rc\0 图 编辑/参考 uTz>I'f )h>dD 现在将脚本代码公布如下，此脚本执行如下几个步骤： yKK9b
