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。 BG|m5f E1r-$gf_ 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: _(zZrUHB enableservice('AutomationServer', true) xU/7}='T enableservice('AutomationServer') rp9?p% :V3z`}Rl 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。 nw4I<Q l1bkhA b
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: :KmnwYm 1. 在FRED脚本编辑界面找到参考. 44NMof8N 2. 找到Matlab Automation Server Type Library HQvJ*U4++ 3. 将名字改为MLAPP GO?hB4 9T xi51,y+(5 3
