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。 9]C%2!Ur, _=Z?5{7S> 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: W6gI# enableservice('AutomationServer', true)
I'`90{I enableservice('AutomationServer') 3c%_RI. ONVhB 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。 -wa"&Q igx~6G* 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: p0rmcP1Ln 1. 在FRED脚本编辑界面找到参考. mq}V @H5 2. 找到Matlab Automation Server Type Library .^dtdFZ8, 3. 将名字改为MLAPP 2cEvsvw> 7Q^p|;~a t!-\:8n
