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。 kX)*:~* G+I->n-s4 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: J- 5kvQi8 enableservice('AutomationServer', true) IfY?P(P enableservice('AutomationServer') _'n]rQ' K%u>'W 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。 f6PYB&<1 b.9[Vf_G 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: #wkSru&LS 1. 在FRED脚本编辑界面找到参考. tC.etoh 2. 找到Matlab Automation Server Type Library w U1[/ 3. 将名字改为MLAPP SEE:v+3| QC6QqcOX wbg?IvY[ 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。 /fU-0a8 en6;I[\ 图 编辑/参考 X}ihYM3y/ V0%a/Hi v
