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。 :5:_Dr< x6|QTO 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: O)r>AdLGn enableservice('AutomationServer', true) S7CD#Y[s enableservice('AutomationServer') &<C&(g{Z *Oy%($' 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。 \BSPv]d dw7h@9\y 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: ` $[`C/h 1. 在FRED脚本编辑界面找到参考. o2LUB)=R' 2. 找到Matlab Automation Server Type Library $U%N$_k? 3. 将名字改为MLAPP 2f9%HX(5 RY*s }f 3N{
