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。 i]%f94 fz=?QEG 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:fx4 enableservice('AutomationServer', true) 25)9R^ enableservice('AutomationServer') p H y K:a8}w>Up 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。 TU0-L35P1 js<d"m* 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: xmv%O&0^} 1. 在FRED脚本编辑界面找到参考. ;7lON-@BI 2. 找到Matlab Automation Server Type Library wQ/* f9 3. 将名字改为MLAPP T;/GHC`{Y sllT1%?
