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。 {wS)M 0^G5 zQlj 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: fEgwQ-] enableservice('AutomationServer', true) 3mCf>qj73 enableservice('AutomationServer') <5fb,@YN =VFPZ 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。 ] l@Mo7|w gOSFvH8FU 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: dPx{9Y<FzU 1. 在FRED脚本编辑界面找到参考. +T,Yf/^Fn 2. 找到Matlab Automation Server Type Library Q"VS;uh.v 3. 将名字改为MLAPP G Ch]5\ `(Eiu$h6V- 5p]Cwj<u 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。 y<0RgG1qp 6.(L8.jv 图 编辑/参考 \])-Bp, Jp#Onl+d6 现在将脚本代码公布如下,此脚本执行如下几个步骤: 8gK
