    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。 qs 52)$  
    g|e^}voRM  
    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: B,|M  
    enableservice('AutomationServer', true) :#c?`>uV  
        enableservice('AutomationServer') n4(w?,w }  
    Joq9.%7Q  
    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 x-CY G?-x  
    <`*6;j.&  
    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: -:cS}I  
    1. 在FRED脚本编辑界面找到参考. M1Od%nz3  
    2. 找到Matlab Automation Server Type Library ]n\WCU ]0  
        3. 将名字改为MLAPP hFj.d]S  
         Y5cUOfYT  
         u#la+/   
    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。 noh3mi

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9"_qa q  
    1. 创建Matlab服务器。 l yO_rZT  
    2. 移动探测面对于前一聚焦面的位置。 ^7F!>!9Ca  
    3. 在探测面追迹光线 d q"b_pr;  
    4. 在探测面计算照度 Qf7]t-Kp  
    5. 使用PutWorkspaceData发送照度数据到Matlab \*!g0C 8 o  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 :[|`&_D9J  
    7. 用Matlab画出照度数据 L'"20=sf  
    8. 在Matlab计算照度平均值 Z UAWSJ,s  
    9. 返回数据到FRED中 0ydAdgD
