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。 0K=Qf69Y [D*J[?yt 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: k1ipvKxp:8 enableservice('AutomationServer', true) XIr{U5$<6 enableservice('AutomationServer') nc3sty1` |ZvNH ~! 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 RL?u n}Qa e$CePLEj 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: hnp`s%e, 1. 在FRED脚本编辑界面找到参考. zq,iLoY[R 2. 找到Matlab Automation Server Type Library 38[)[{G)Hv 3. 将名字改为MLAPP nkCecwzr- jrIA]K6 mND XzT& 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。 8|1`Tn}o T?W[Z_D 图 编辑/参考 _LJ5o_-N 7m@
