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。 U*7x81v?j sk7]s7 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: Pd;G c@'~ enableservice('AutomationServer', true) cSYMnB enableservice('AutomationServer') 8Cw3b\ne w7b\?]}@ 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。 N%!{n7`N: WGHf?G/s 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: sI6coe5n 1. 在FRED脚本编辑界面找到参考. p;.M. 2. 找到Matlab Automation Server Type Library !TLJk]7uC 3. 将名字改为MLAPP %`}nP3 Cm;M;
