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。 )!A 2> }wfI4?}j} 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： AuAT]` enableservice('AutomationServer', true) ?;^5ghY$ enableservice('AutomationServer') QWw "K$l  _lP4}9 p 结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 -bA!PeI ugI#ZFjJWE 在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： j{)~Q D ? 1. 在FRED脚本编辑界面找到参考. + 8f>^*:u 2. 找到Matlab Automation Server Type Library 9<l-NU9 _ 3. 将名字改为MLAPP dKm`14f]@G g5}lLKT %K?iNe 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 'irGvex lUHtjr 图 编辑/参考 r 1G8]a gO ;g9% & 现在将脚本代码公布如下，此脚本执行如下几个步骤： y"-{$ N
