    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。 edh<L/%D  
    IR*:i{  
    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: 4(\7Or(''  
    enableservice('AutomationServer', true) |n.ydyu`  
    enableservice('AutomationServer') I,!>ZG@6  
    ^ px)W,O  
    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 P+;@?ofB  
    ~uu~NTz  
    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:  tD}HL_  
    1. 在FRED脚本编辑界面找到参考. aV?r%'~Z  
    2. 找到Matlab Automation Server Type Library 7j%sM&  
    3. 将名字改为MLAPP w^QqYUL${  
    TZk.h8  
    Dv+:d4|"  
    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。 l ~ /y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~b{j`T  
    1. 创建Matlab服务器。 ;V3d"@R,  
    2. 移动探测面对于前一聚焦面的位置。 NbW5a3=  
    3. 在探测面追迹光线 Y{ 2xokJ N  
    4. 在探测面计算照度 G6x2!Ny  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9<I;9.1S?^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ecy41y'~:  
    7. 用Matlab画出照度数据 S~ 3|  
    8. 在Matlab计算照度平均值 ,@*`2I>`  
    9. 返回数据到FRED中 q CB9z
