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。 z})H$]: $ R:0Fv9bwS 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: qqS-0U2 enableservice('AutomationServer', true) TLPy/, enableservice('AutomationServer') Rk2ZdNc\ jEit^5^5| 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。 q,QMvUK: :==kC672 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: AG/nX?u7)t 1. 在FRED脚本编辑界面找到参考. ]rZ"5y 2. 找到Matlab Automation Server Type Library D@>P%k$$s> 3. 将名字改为MLAPP W_O,Kao |X~T</{8i \P&'4y~PL 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。 #++MoW}'g @D[;$YEk 图 编辑/参考 q<,?:g$k nU[ROy5 现在将脚本代码公布如下,此脚本执行如下几个步骤: vh
