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。 i.byHz?/ DsFrA] 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: fitm* enableservice('AutomationServer', true) da2BQ; enableservice('AutomationServer') bo@1c0 'rCwPsI&4 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。 Crey}A/N +$<m ;@mZ 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 6w@l#p 1. 在FRED脚本编辑界面找到参考. ^Nc\D7( l 2. 找到Matlab Automation Server Type Library 12rr:(#%s 3. 将名字改为MLAPP Kk/qd)nk `#l_`j=r$ 5$O@+W!?@ 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。 pWQ?pTh ?EtK/6dJZt 图 编辑/参考 2=U4'C4# fC81(5 现在将脚本代码公布如下,此脚本执行如下几个步骤: :/1WJG:! 1. 创建Matlab服务器。 4ci
