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。 D;C5,rNt J/[7d?hI/ 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: hg&u0AQ2 enableservice('AutomationServer', true) jrcc enableservice('AutomationServer') !7Uu]m69n +gNX7xuY 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。 %IU4\ZY> @7X\tV.Z 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:
