    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。 h)~=Dm  
    j!7`]  
    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: Hf'G8vW  
    enableservice('AutomationServer', true) *Av"JAX  
        enableservice('AutomationServer') @(P=Eh  
    x21dku<6K[  
    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 %Qg+R26U  
    +&zYZA8v  
    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: LjL[V'JL  
    1. 在FRED脚本编辑界面找到参考. nJPyM/p  
    2. 找到Matlab Automation Server Type Library 1qV@qz  
        3. 将名字改为MLAPP H|cNH=  
         >!_Xgw  
         1n%?@+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。 1B),A~Ip

    现在将脚本代码公布如下,此脚本执行如下几个步骤: VMoSLFp^R  
    1. 创建Matlab服务器。 \!]Ua.e<  
    2. 移动探测面对于前一聚焦面的位置。 s1|/S\   
    3. 在探测面追迹光线 pJN${  
    4. 在探测面计算照度 Y#!h9F  
    5. 使用PutWorkspaceData发送照度数据到Matlab XqM3<~$  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 =^H4Yck/5  
    7. 用Matlab画出照度数据 fgihy  
    8. 在Matlab计算照度平均值 r`c_e)STO  
    9. 返回数据到FRED中 R/"x}B1d
