FRED如何调用Matlab
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。 Iw.!*0$ uh.;Jj; 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: 2z#S|$ enableservice('AutomationServer', true) }wp/,\_
> enableservice('AutomationServer') &L+.5i
XC;Icr) 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。 }.'rhR+ )=iv3nF?6N 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: ?ZGsh7<k 1. 在FRED脚本编辑界面找到参考. S2\;\?]^~ 2. 找到Matlab Automation Server Type Library 'Nt)7U>oC9 3. 将名字改为MLAPP @.i#uMWF` }
