    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。 R^GLATM  
    |79n 1;+\?  
    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: `L {dF  
    enableservice('AutomationServer', true) /qO?)p3gk  
        enableservice('AutomationServer') oW8 hC  
    }@jT-t]P  
    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 4vf,RjB-5  
    qjd8Q  
    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: u9)<i]2  
    1. 在FRED脚本编辑界面找到参考. b+mh9q'5E  
    2. 找到Matlab Automation Server Type Library Qrt> vOUE7  
        3. 将名字改为MLAPP hG.~[#[&6  
         W\<p`xHk  
         xZ(VvINL'  
    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。 Fd@:*ER

    2. 移动探测面对于前一聚焦面的位置。 S t0AV.N1

        6. 使用PutFullMatrix发送标量场数据到Matlab中 6GtXM3qtS  
    7. 用Matlab画出照度数据 IBr|A
