FRED如何调用Matlab
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。 $&C(oh$: bSr 'ji 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: O|>1~^w enableservice('AutomationServer', true) {a3kn\6H0 enableservice('AutomationServer') pq[mM!;#v
V{h@nhq 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。 bNROXiX AIm$in`P 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: /SXz_e 1. 在FRED脚本编辑界面找到参考. ;ULC|7rL 2. 找到Matlab Automation Server Type Library 2*citB{ 3. 将名字改为MLAPP 99 !{[gOv >jX
