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。 | V Ps5 NlXHOUw)u 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: <\!+J\YTA enableservice('AutomationServer', true) Ug*:o d enableservice('AutomationServer') li;Np5P
!q=ej^(S 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。 KArt4+31 4]0|fi3}> 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: YbB8D- 1. 在FRED脚本编辑界面找到参考. b/cc\d < 2. 找到Matlab Automation Server Type Library }+G6` Zd 3. 将名字改为MLAPP SjV;&
