    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。 -r6LndQs  
    o!|TCwt  
    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: >J@hqW  
    enableservice('AutomationServer', true) VW\~OH  
    enableservice('AutomationServer') 1V2"sE  
    Pb@9<NXm'  
    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 0D48L5kH#'

    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: *'ex>4^  
    1. 在FRED脚本编辑界面找到参考. `n~bDG>  
    2. 找到Matlab Automation Server Type Library 4w0Y(y  
    3. 将名字改为MLAPP ADN

    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。 t0gLz J

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =lqGt.x  
    1. 创建Matlab服务器。 H-1y2AQ  
    2. 移动探测面对于前一聚焦面的位置。 :g=z}7!s  
    3. 在探测面追迹光线 N6_<[`  
    4. 在探测面计算照度 M `bEnu  
    5. 使用PutWorkspaceData发送照度数据到Matlab xQ7-4 N,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (E(kw="  
    7. 用Matlab画出照度数据 J^ BC  
    8. 在Matlab计算照度平均值 2kU=9W6ND  
    9. 返回数据到FRED中 ^3  '7
