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。 Lk8W&|;0| <IHFD^3|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: HL}sqcp enableservice('AutomationServer', true) ?-RoqF enableservice('AutomationServer') 8VAYIxRv c"QkE* 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。 ;?O883@r8 %O4}i@Fe 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: E<98ahZ?l 1. 在FRED脚本编辑界面找到参考. ~_# Y,)S!z 2. 找到Matlab Automation Server Type Library d-#u/{jG) 3. 将名字改为MLAPP ]Lb?#S p'uqh
