    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。 PAG.],"D  
    m>dZ n  
    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: pE.f}  
    enableservice('AutomationServer', true) X :2%U  
    enableservice('AutomationServer') #Hm*<s.  
    6f1%5&si  
    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!# (.P  
    O%RkU?ME  
    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: U^jxKBq^  
    1. 在FRED脚本编辑界面找到参考. Uawf,57v<  
    2. 找到Matlab Automation Server Type Library g%()8QxE1  
    3. 将名字改为MLAPP c32IO&W4

    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。 h%'4V<V

    1. 创建Matlab服务器。 V=yRE  
    2. 移动探测面对于前一聚焦面的位置。 JNhHQvi\  
    3. 在探测面追迹光线 \~V Z Y  
    4. 在探测面计算照度 5Z2E))UU  
    5. 使用PutWorkspaceData发送照度数据到Matlab }6/L5j:+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h{zE;!+)D  
    7. 用Matlab画出照度数据 F O"8B  
    8. 在Matlab计算照度平均值 5f+ziiZ  
    9. 返回数据到FRED中 ua$H"(#c
