    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&T0Ls#4  
    0yr=$F(]s  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: s8Kf$E^?e.  
    enableservice('AutomationServer', true) ?;@xAj  
        enableservice('AutomationServer') _yY(&(]#  
    }[XzM /t  
    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 P.Pw .[:3

    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: j_S///  
    1. 在FRED脚本编辑界面找到参考. |P7c {  
    2. 找到Matlab Automation Server Type Library d!kiWmw,  
        3. 将名字改为MLAPP #A<|&#hh  
         LW6&^S?4{

    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。 Jv1igA21_h

    4. 在探测面计算照度 @k:f(c

        6. 使用PutFullMatrix发送标量场数据到Matlab中 fTiqY72h  
    7. 用Matlab画出照度数据 ?h UC#{
