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。 Y6 &w0~?! PW~+ =, 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： :W J [a# enableservice('AutomationServer', true) M)#aX| %Mh enableservice('AutomationServer') 2 D>WIOX  fOtL6/? 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。 u-$(TyDEl| 3g`uLA X>u 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： 1c8 J yp 1. 在FRED脚本编辑界面找到参考. :4;ZO~eq! 2. 找到Matlab Automation Server Type Library oM M`7wJw 3. 将名字改为MLAPP nM>oG'm[n :na9PW`TC B#N(PvtE 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。 0V@u] 7H %>\ ^A^ 图 编辑/参考 Xk8+m> 4
