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。 |>Z&S=\I) gm(De9u 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: 6$;L]<$W> enableservice('AutomationServer', true) (=`Z0)= enableservice('AutomationServer') Z(KmS( O@nqHZ 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。 `bzr_fJ {>wI8 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: Jc`Rs"2 1. 在FRED脚本编辑界面找到参考. i3D<`\;r 2. 找到Matlab Automation Server Type Library d3Y(SPO 3. 将名字改为MLAPP Wgav>7!9 F%9cS
