    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。 {*g{9`   
    FYu30  
    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: thX4-'i  
    enableservice('AutomationServer', true) ^?\|2H  
        enableservice('AutomationServer') P.k>6T<U>  
    Voq/0,d  
    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 H/Ql

    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: 0t"Iq71/  
    1. 在FRED脚本编辑界面找到参考. (E,[Ad,$  
    2. 找到Matlab Automation Server Type Library qe?Ns+j<d  
        3. 将名字改为MLAPP @q># ]8

    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。 VK,{Mu=.9

    1. 创建Matlab服务器。 _*{Lha  
    2. 移动探测面对于前一聚焦面的位置。 Z 5P4 H  
    3. 在探测面追迹光线 j"pyK@v2B  
    4. 在探测面计算照度 E;'{qp  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7B5b +  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 XhWo~zh"  
    7. 用Matlab画出照度数据 1=9GV+`n  
    8. 在Matlab计算照度平均值 CK|AXz+EN
