    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。 :MGIp%3  
    kQ|phtbI  
    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: Mr@{3do$  
    enableservice('AutomationServer', true) {"_V,HmEF+  
    enableservice('AutomationServer') =- !B4G$  
    -Zqw[2Q4  
    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 ;pG5zRe  
    {?X9juc/#  
    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: .]/k#Hv  
    1. 在FRED脚本编辑界面找到参考. %V92q0XW  
    2. 找到Matlab Automation Server Type Library W7w*VD|  
    3. 将名字改为MLAPP Fyc":{Jd  
    V5+|H1=  
    k>#-NPU$  
    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。 d6A+pa'2

    3. 在探测面追迹光线 P?zL`czWd  
    4. 在探测面计算照度 v&xhS yZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab l>pnY%(A  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Rc}#4pM8  
    7. 用Matlab画出照度数据 nz Klue  
    8. 在Matlab计算照度平均值 p+Fh9N<F9  
    9. 返回数据到FRED中 1t7T\~ +F
