    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。 _|^cudRv  
    *OM+d$l!  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: e-E0Bp  
    enableservice('AutomationServer', true) :<QmG3F  
        enableservice('AutomationServer') .#Vup{.  
    8u|F %Sg  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 sa?Ul)L2  
    QZZt9rA;  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ",, W1]"%  
    1. 在FRED脚本编辑界面找到参考. ov$S   
    2. 找到Matlab Automation Server Type Library $R&K-;D/8  
        3. 将名字改为MLAPP %3kS;AaA  
         V'M#."Of/  
         #_pQS}$  
    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。 $:}sm0;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: DnP "7}v  
    1. 创建Matlab服务器。 gcI?)F   
    2. 移动探测面对于前一聚焦面的位置。 YJm64H,[  
    3. 在探测面追迹光线 v$d^>+Y#  
    4. 在探测面计算照度 O[<YYL 0  
    5. 使用PutWorkspaceData发送照度数据到Matlab \c(Z?`p]R1  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 VRQD  
    7. 用Matlab画出照度数据 is6M{K3  
    8. 在Matlab计算照度平均值 7;rf$\-&  
    9. 返回数据到FRED中 v!WkPvU
