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。 llsfTrp i 3SHg\~Z 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: ctJE+1#PH enableservice('AutomationServer', true) !g.? enableservice('AutomationServer') _-F s#f8 VD\=`r)nT 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。 b_):MQ1{ gzg_>2Sj 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: zv"Z DRW 1. 在FRED脚本编辑界面找到参考. n-OL0$Xu 2. 找到Matlab Automation Server Type Library Xs?o{]Fe 3. 将名字改为MLAPP
YrKWA !Rt>xD :/Qq@]O> 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。 I!?}jo3 ]g&TKm 图 编辑/参考 !v0LBe4 1sH&
