FRED案例-FRED如何调用Matlab
$["HC-n?.k 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。 5P"R'/[PA_ 1ruI++P 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: h%ys::\zF enableservice('AutomationServer', true) YRX^fZ-b enableservice('AutomationServer') ?{J1Uw<
$S|+U}]C 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。 a'?;;ZC- t~/:St 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: Zja3HGL 1. 在FRED脚本编辑界面找到参考. 4A6Y
\Z XI 2. 找到Matlab Automation Server Type Library t:fz%IOe 3. 将名字改为MLAPP Cd
