    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。 5nTY ?<x`k  
    rEHkw '  
    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: %7#-%{  
    enableservice('AutomationServer', true) u$*56y   
    enableservice('AutomationServer') E Q4KV  
    X/z6"*(|/  
    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 chV9_(8  
    I8+~ &V}  
    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: 1rKlZsZ#*  
    1. 在FRED脚本编辑界面找到参考. JT "B>y>  
    2. 找到Matlab Automation Server Type Library _<=S_ <$2  
    3. 将名字改为MLAPP }Ow>dV?

    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。 6(]tYcC

    3. 在探测面追迹光线 Z4A!U~  
    4. 在探测面计算照度 FP0G]=ME  
    5. 使用PutWorkspaceData发送照度数据到Matlab R+nMy=I%8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 MZTx:EN!  
    7. 用Matlab画出照度数据 R)M_|ca  
    8. 在Matlab计算照度平均值 )I^2k4Cg"
