    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。 0{U]STj  
    t ?Njw7  
    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: &"~,V6,q  
    enableservice('AutomationServer', true) L~?,6  
    enableservice('AutomationServer') ^^t]vojX  
    IxK 3,@d  
    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 e$p1Th*|]4

    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: 9}'l=b:Jms  
    1. 在FRED脚本编辑界面找到参考. kp#c:ym  
    2. 找到Matlab Automation Server Type Library [7SI<xkv  
    3. 将名字改为MLAPP @vQ;>4i.

    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。 ^G7n#

    8. 在Matlab计算照度平均值 ~3*ZG
