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。 S.+)">buH bOCdf"!g 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: j$*]'s&_hZ enableservice('AutomationServer', true) DytOS}/^9 enableservice('AutomationServer') 3zb;q@JV m_H$fioha, 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。 }6]V*Kn, s)HbBt- 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: <69/ZI),Y{ 1. 在FRED脚本编辑界面找到参考. g 1\4Jb 2. 找到Matlab Automation Server Type Library OwP9=9}; 3. 将名字改为MLAPP :^SpKe(7 G'(
