    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。 #E^%h  
    JGn@)!$+/  
    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: >/6v` 8F  
    enableservice('AutomationServer', true) U^VFHIm  
    enableservice('AutomationServer') 6:v8J1G(<  
    qI<*Cze  
    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 ?TMo6SU  
    PgB=<#9  
    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: a+A/l  
    1. 在FRED脚本编辑界面找到参考. K.o?g?&<  
    2. 找到Matlab Automation Server Type Library @`%.\_  
    3. 将名字改为MLAPP tK g%5;v

    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。 "y "C#:5

    1. 创建Matlab服务器。 @a%,0Wn  
    2. 移动探测面对于前一聚焦面的位置。 %04>R'mN  
    3. 在探测面追迹光线 jd]MC*%  
    4. 在探测面计算照度 WVy"MD  
    5. 使用PutWorkspaceData发送照度数据到Matlab fN0D\Mu!)b  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 F:hJ^:BP  
    7. 用Matlab画出照度数据 ?B@hCd)  
    8. 在Matlab计算照度平均值 n0 !S;HH-  
    9. 返回数据到FRED中 8'^eH1d'
