    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。 D}U gC\u  
    nGur2}>n  
    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: ;Zn&Nc7  
    enableservice('AutomationServer', true) uO1^nK  
    enableservice('AutomationServer') Mhc5<~?  
    ,uO_C(G/i  
    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 YdUcO.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: 6X$nZM|g,  
    1. 在FRED脚本编辑界面找到参考. &%eM  
    2. 找到Matlab Automation Server Type Library a>+m_]*JZ  
    3. 将名字改为MLAPP Pon0(:#1  
    :^FH.6}x  
    dCLNZq h6  
    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。 JOs kf(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u#Bj#y!  
    1. 创建Matlab服务器。 Ak$9\Sl  
    2. 移动探测面对于前一聚焦面的位置。 ;";>7k/}  
    3. 在探测面追迹光线 +?{LLD*2e  
    4. 在探测面计算照度 =\\rk,F  
    5. 使用PutWorkspaceData发送照度数据到Matlab Bx.hFEL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =5:kV/p  
    7. 用Matlab画出照度数据 17w{hK4o8O  
    8. 在Matlab计算照度平均值 1f?Fuw  
    9. 返回数据到FRED中 U.ZA%De
