    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。 s`#g<_{X  
    &uP,w#  
    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: 0Sx$6:-~  
    enableservice('AutomationServer', true) 7fE U5@  
        enableservice('AutomationServer') _O#R,Y2#  
    zPm|$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 wjy<{I  
    vb.}SG>  
    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: gUGMoXSTI|  
    1. 在FRED脚本编辑界面找到参考. :yxP3e%rp  
    2. 找到Matlab Automation Server Type Library yd|ao\'=  
        3. 将名字改为MLAPP Y+)qb);

    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。 jEMnre3/

    1. 创建Matlab服务器。 ,,8'29yEq  
    2. 移动探测面对于前一聚焦面的位置。 U5:5$T,C  
    3. 在探测面追迹光线 {&TP&_|H  
    4. 在探测面计算照度 YgV"*~  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1$_|h@  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 yU|=)p5  
    7. 用Matlab画出照度数据 T3bYj|rh=  
    8. 在Matlab计算照度平均值 z"\<GmvB  
    9. 返回数据到FRED中 dt5`UBvUg
