    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。 9m\)\/V  
    # #k #q=4  
    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: Z!wD~C"D73  
    enableservice('AutomationServer', true) u}Ei_ O<z  
    enableservice('AutomationServer') u?q&K|  
    v7 8&[  
    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 5mI?pfm  
    j7@!J7S  
    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: 09R,'QJ|  
    1. 在FRED脚本编辑界面找到参考. fd?bU|I_2  
    2. 找到Matlab Automation Server Type Library *he7BUO  
    3. 将名字改为MLAPP kU #:I9PO

    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。 =QrA0kQR

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <9@&oN+T  
    1. 创建Matlab服务器。 Z,0O/RFJ.q  
    2. 移动探测面对于前一聚焦面的位置。 1KW3l<v-6  
    3. 在探测面追迹光线 3%XG@OgP  
    4. 在探测面计算照度 UG6M9  
    5. 使用PutWorkspaceData发送照度数据到Matlab TT|-aS0l(u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w`M]0'zls  
    7. 用Matlab画出照度数据 >W8bWQ^fK  
    8. 在Matlab计算照度平均值 *I=_*LoG2  
    9. 返回数据到FRED中 4$%`Qh>yA
