    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。 ]DOX?qI i  
    xgpi-l  
    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: T,]7ICF#  
    enableservice('AutomationServer', true) T.@aep\"  
    enableservice('AutomationServer') 3{""58  
    _9JhL:cY  
    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 &{>cZh}\  
    /e7O$L)   
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: P/c&@_b  
    1. 在FRED脚本编辑界面找到参考. lLp^Gt^}w(  
    2. 找到Matlab Automation Server Type Library 7N-w eX  
    3. 将名字改为MLAPP 'qjeXqGH$  
    VTG9$rQZ  
    94+KdHAo^M  
    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。 dQ_!)f&w1

    4. 在探测面计算照度 q8^^H$<Db  
    5. 使用PutWorkspaceData发送照度数据到Matlab MP_'D+LS  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Gs9:6  
    7. 用Matlab画出照度数据 twP,cyR  
    8. 在Matlab计算照度平均值 LUuZ9$t0J"  
    9. 返回数据到FRED中 \<y`!"c
