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。 HI[Pf%${ /?V- 配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： Tz&h[+ 6` enableservice('AutomationServer', true) 7}pg7EF3z enableservice('AutomationServer') q RRvZhf  n(sseQ|\ 结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 1I40N[ PE) cNye@}$lu 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： y<c7 RK] 1. 在FRED脚本编辑界面找到参考. v^Rw9*w{ 2. 找到Matlab Automation Server Type Library |<MSV KW 3. 将名字改为MLAPP 7j88^59 {+E nJ" FbXur- et^ 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。 s(r4m/ ~y,m7%L 图 编辑/参考 BKYyc6 iE ,vAcri
