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。 r|WoM39bp sDH|k@K 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: F; IG@ & enableservice('AutomationServer', true) zJfoU*G/B enableservice('AutomationServer') I 2!0,1Q Q(}TN,N 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。 <p'~$vK oR=^NEJv 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ?6bk&"T? 1. 在FRED脚本编辑界面找到参考. @lau?@$ja 2. 找到Matlab Automation Server Type Library FJN,er~T[ 3. 将名字改为MLAPP
