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。 NdJ]\>5oN, k@fxs]Y_L 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: 6DHZ,gWq enableservice('AutomationServer', true) b6;MTz*k> enableservice('AutomationServer') rui 8x4c 0<uL0FOT 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。 \=RV?mI3?
