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。 Rlc$2y@pU KQ0Zy 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: ``*iK enableservice('AutomationServer', true) =6FA(R|QU enableservice('AutomationServer') Pn:L=* eXo7_# 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。 cMxuG'{=. r8.R?5F@ 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: v@_}R_pX 1. 在FRED脚本编辑界面找到参考. u#9 H 2. 找到Matlab Automation Server Type Library cXM4+pa=% 3. 将名字改为MLAPP $['_m~
