    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 O G[^T  
    kqo4 v;r  
    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: IIBS:&;+-  
    enableservice('AutomationServer', true) 152s<lu1Z  
    enableservice('AutomationServer') J[S!<\_!  
    /FPO'} 6i  
    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 F,pKt.x  
    KE5>O1  
    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: I7Abf7>*Q  
    1. 在FRED脚本编辑界面找到参考. ph!h8@e  
    2. 找到Matlab Automation Server Type Library 5K$<Ad4$b  
    3. 将名字改为MLAPP p g_H'0R

    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。 2* T Ir

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TPKD'@:x  
    1. 创建Matlab服务器。 hPgYKa8u  
    2. 移动探测面对于前一聚焦面的位置。 }K,3SO(:  
    3. 在探测面追迹光线  fWs*u[S  
    4. 在探测面计算照度 z_{_wAuY  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6^BT32,'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z" ?WT$  
    7. 用Matlab画出照度数据 j:2 F97  
    8. 在Matlab计算照度平均值 m&(qr5>b  
    9. 返回数据到FRED中 8.IenU9
