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$8TT8+- +-a&2J;J' 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: a{!r`>I\f enableservice('AutomationServer', true) gFPi7 o1 enableservice('AutomationServer') Kv{8iAB#c U{ ;l0 2S 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。 (9 gOtJ }#v{`Sn%^C 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: {S<>&?XB 1. 在FRED脚本编辑界面找到参考.
