    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。 `BmnXWMgx  
    L#S W!  
    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: ]9_gbQ   
    enableservice('AutomationServer', true) :E}y Pcw  
    enableservice('AutomationServer') <T>s;b  
    "{8j!+]4i  
    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 h: yJ  
    NU=2*gM  
    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: s[GHDQ;!  
    1. 在FRED脚本编辑界面找到参考. 1G]D:9-?  
    2. 找到Matlab Automation Server Type Library 7R:j^"I@  
    3. 将名字改为MLAPP brp3xgQ`]

    {|>'(iqH"w  
    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。 N3$1f$`

    3. 在探测面追迹光线 \^6[^\@[  
    4. 在探测面计算照度 /"J 6``MV  
    5. 使用PutWorkspaceData发送照度数据到Matlab j7)mC4o:%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 a/ uo)']B  
    7. 用Matlab画出照度数据 %|JiFDjp  
    8. 在Matlab计算照度平均值 Sm<*TH!\n_
