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。 9NH"Ik* o<`)cb } 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: jL$&]sQ`O) enableservice('AutomationServer', true) E"ju<q/Q enableservice('AutomationServer') P!?Je/Tz] O[p;IG` 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。 G)(\!0pNZ Qm|Q0u 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: >*xa\ve 1. 在FRED脚本编辑界面找到参考. j1!P:( 2. 找到Matlab Automation Server Type Library V?g@pnN" 3. 将名字改为MLAPP H].G%,2' ]Gw?
