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。 P^BSl7cT FT gt$I 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: qV$0 ";d enableservice('AutomationServer', true) 7B)@ aUj$ enableservice('AutomationServer') 4J[csU Tkh?F5l 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。 &b19s=Z, BJZGQrsz 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: w- wJhc| 1. 在FRED脚本编辑界面找到参考. l2LO,j} 2. 找到Matlab Automation Server Type Library 0}Qd 3. 将名字改为MLAPP U}-hV@y
