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。 5vo5t0^o S2,tv 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: 8k|&&3_[? enableservice('AutomationServer', true)
q-|j
= enableservice('AutomationServer') '%y5Dh @4xV3Xkf&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。 $3c9iVK~_ q\]"}M8 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: S<nf"oy_K 1. 在FRED脚本编辑界面找到参考. ` 5lW 2. 找到Matlab Automation Server Type Library o<Y[GW1pg 3. 将名字改为MLAPP &@rXt!
