    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。 Q6e'0EIKC  
    3N)Ycf8  
    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: J7 Oa})-+'  
    enableservice('AutomationServer', true) Lqz}&A   
    enableservice('AutomationServer') 8iII) +  
    bahc{ZC2  
    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 J,(U<%n

    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: Azdz3/  
    1. 在FRED脚本编辑界面找到参考. OXa5Jg}=  
    2. 找到Matlab Automation Server Type Library w|K(>5nz

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 etQx>U

    1. 创建Matlab服务器。 ^bY^x+d  
    2. 移动探测面对于前一聚焦面的位置。 7#~m:K@

    6. 使用PutFullMatrix发送标量场数据到Matlab中 NXV~[
