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。 :Mss"L820 'F'v/G~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： ,!"\L~6 enableservice('AutomationServer', true) ;c5Q" enableservice('AutomationServer') Z3K~C_0Cnu  e[t +pnRh 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。 O! !Ne'I tlU&p' 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： ER:)Fk>_ 1. 在FRED脚本编辑界面找到参考. kc d~`+ C 2. 找到Matlab Automation Server Type Library tA+ c 3. 将名字改为MLAPP v)(tB7&`= u$c)B<.UR #D"fCVIS 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。 gB !K{ Io' z.f~wAT@< 图 编辑/参考 8=^o2& &xF 2!t` 现在将脚本代码公布如下，此脚本执行如下几个步骤： A &i
