    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。 bTZ>@~$  
    C=fsJ=a5;  
    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: $/u1chf  
    enableservice('AutomationServer', true) 5Z/yhF.{  
        enableservice('AutomationServer') Dt.0YKF  
    8YNu<   
    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 =%!e(N'p  
    MaZM%W8Z  
    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: A0G)imsW:_  
    1. 在FRED脚本编辑界面找到参考. YiD-F7hf.*  
    2. 找到Matlab Automation Server Type Library kmryu=  
        3. 将名字改为MLAPP "r u]?{v  
         ]b3/Es+  
         >A-<ZS*N  
    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。 M70c{s`w5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h@=7R  
    1. 创建Matlab服务器。 ]1m"V;vZ  
    2. 移动探测面对于前一聚焦面的位置。 J , V  
    3. 在探测面追迹光线 MR`:5e  
    4. 在探测面计算照度 wMGk!N  
    5. 使用PutWorkspaceData发送照度数据到Matlab OFA{ KZga  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 VZ$=6CavH  
    7. 用Matlab画出照度数据 7W"/ N#G  
    8. 在Matlab计算照度平均值 [r(Qs|  
    9. 返回数据到FRED中 #O"
