    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。 p_I^7 $  
    -))S  
    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: e@P(+.Ke  
    enableservice('AutomationServer', true) )Fx]LeI;  
    enableservice('AutomationServer') @k i|# ro  
    35l%iaj]G5  
    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 tK;xW

    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: sJLOz>  
    1. 在FRED脚本编辑界面找到参考. @)d_zWE  
    2. 找到Matlab Automation Server Type Library 7"!`<5o^  
    3. 将名字改为MLAPP )#i@DHt=  
    M P8Sd1_=

    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。 1["i,8zB

    1. 创建Matlab服务器。 *47/BLys<  
    2. 移动探测面对于前一聚焦面的位置。 JU17]gQ  
    3. 在探测面追迹光线 l qfTF  
    4. 在探测面计算照度 R=~%kt_n  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z3&}C h  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JOuyEPy  
    7. 用Matlab画出照度数据 8?iI;(  
    8. 在Matlab计算照度平均值 Xqw}O2QQ1  
    9. 返回数据到FRED中 _^W;J/He
