    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。 nYE' 'g+x  
    d&owS+B{48  
    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: q}r{%ypf  
    enableservice('AutomationServer', true) \T:*tgU  
    enableservice('AutomationServer') z0-[ RGg  
    MD+e!A#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 fpA%: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: ]q":ta!f  
    1. 在FRED脚本编辑界面找到参考. 3[cGSI"+  
    2. 找到Matlab Automation Server Type Library dhCrcYn  
    3. 将名字改为MLAPP wN2D{Jj  
    s*9lYk0

    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。 |Ca %dg9$@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: bqcwZ6r<  
    1. 创建Matlab服务器。 *Kmo1>^  
    2. 移动探测面对于前一聚焦面的位置。 Zk<Y+!  
    3. 在探测面追迹光线 {osadXd C  
    4. 在探测面计算照度 \]Y=*+{  
    5. 使用PutWorkspaceData发送照度数据到Matlab Dk#4^`qp1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &j!q9F  
    7. 用Matlab画出照度数据 /`+ubFXc  
    8. 在Matlab计算照度平均值 ohlCuH 3  
    9. 返回数据到FRED中 m_C#fR /I
