    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。 0" F\ V  
    rL,kDSLs  
    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: C1==a FD  
    enableservice('AutomationServer', true) B7.<A#y2  
    enableservice('AutomationServer') 3Yf~5csY  
    PDpuHHB  
    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 ,7Dm p7

    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: (c S'Nm5  
    1. 在FRED脚本编辑界面找到参考. 2)Q%lEm`SP  
    2. 找到Matlab Automation Server Type Library  eIj2(q9  
    3. 将名字改为MLAPP ]tNB^

    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。  p ~pl|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O[8wF86R  
    1. 创建Matlab服务器。 =d$m@rc0r  
    2. 移动探测面对于前一聚焦面的位置。 z s\N)LyM  
    3. 在探测面追迹光线 8&:dzS  
    4. 在探测面计算照度 t(99m=9>  
    5. 使用PutWorkspaceData发送照度数据到Matlab <9[>+X  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 62o nMY  
    7. 用Matlab画出照度数据 h ^Wm03w
