    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。 yn{U/+  
    }iR!uhi#  
    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: yMf["AvG  
    enableservice('AutomationServer', true) uTP4r  
        enableservice('AutomationServer') Js !Zk\O  
    `Y7&}/OM  
    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 `ln= D$  
    /A`Ly p#  
    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: ':,p6  
    1. 在FRED脚本编辑界面找到参考. )W![TIp  
    2. 找到Matlab Automation Server Type Library p2Fi(BW*q  
        3. 将名字改为MLAPP fOO[`"'Pq  
         ;#?+i`9'q  
         ,An*w_  
    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。 cUr'mb

    现在将脚本代码公布如下,此脚本执行如下几个步骤: e+O0l  
    1. 创建Matlab服务器。 ekuRGG  
    2. 移动探测面对于前一聚焦面的位置。 oJEjg>%n  
    3. 在探测面追迹光线 e@{8G^o>D  
    4. 在探测面计算照度 5nG$6Hw  
    5. 使用PutWorkspaceData发送照度数据到Matlab '=m ?l  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 "8`f x  
    7. 用Matlab画出照度数据 E+E.z?>S  
    8. 在Matlab计算照度平均值 KP!ctlP~  
    9. 返回数据到FRED中 gUxJ>~
