    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。 ppA8c6  
    VF.S)='>Eu  
    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: *L_wRhhk  
    enableservice('AutomationServer', true) 4V5*6O9(u  
        enableservice('AutomationServer') NunT2JP.  
    Dl6zl6q?  
    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 %## bg<  
    wB{-]\H`\  
    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: =6:Iv"<  
    1. 在FRED脚本编辑界面找到参考. 4 @h6|=  
    2. 找到Matlab Automation Server Type Library uIBV1Qz  
        3. 将名字改为MLAPP &bb*~W-

         ^+&}:9Ml  
    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。 Sob+l'U$

    现在将脚本代码公布如下,此脚本执行如下几个步骤: xk9]jQ7  
    1. 创建Matlab服务器。 ;x"B ):?\  
    2. 移动探测面对于前一聚焦面的位置。 ^z1WPI  
    3. 在探测面追迹光线 qSR %#  
    4. 在探测面计算照度 p /:L;5F  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z1zC@z4sUj  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 F7d f  
    7. 用Matlab画出照度数据 aqlYB7  
    8. 在Matlab计算照度平均值 =Ur/v'm  
    9. 返回数据到FRED中 X$<?:f-
