    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。 OTE<x"=h  
    n26>>N  
    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: "7d.i(vw  
    enableservice('AutomationServer', true) ,%Z&*n  
        enableservice('AutomationServer') x{Sd P$  
    pqeL%="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 ~0ooRUWU7

    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: r4?b0&Xq  
    1. 在FRED脚本编辑界面找到参考. >t0%?wj)Y  
    2. 找到Matlab Automation Server Type Library +2Ql~w@$^l  
        3. 将名字改为MLAPP ]^ #`j

    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。 Q&PB]D{

    4. 在探测面计算照度 "yW&<7u1  
    5. 使用PutWorkspaceData发送照度数据到Matlab [4XC #OgA  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 |1l&@#j!2  
    7. 用Matlab画出照度数据 ` 8UWE {  
    8. 在Matlab计算照度平均值 j#VIHCzlr  
    9. 返回数据到FRED中 <0 uOq
