    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。 lY,1 w  
    lJ2/xE]  
    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: 5q*~h4=r7  
    enableservice('AutomationServer', true) eesLTy D2_  
    enableservice('AutomationServer') yL,B\YCf8  
    PhdL@Mr  
    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 @Kb~!y@G

    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: FX%E7H  
    1. 在FRED脚本编辑界面找到参考. _)\,6| #  
    2. 找到Matlab Automation Server Type Library ,)m-nZ5  
    3. 将名字改为MLAPP 6XqO' G

    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。 K~N[^pF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 7]53GGNO  
    1. 创建Matlab服务器。 %^A++Z$`  
    2. 移动探测面对于前一聚焦面的位置。 ~Dh}E9E:  
    3. 在探测面追迹光线 *]u/,wCB  
    4. 在探测面计算照度 2?&ptN) `N  
    5. 使用PutWorkspaceData发送照度数据到Matlab xrd ^vE  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J?DyTs3 Z  
    7. 用Matlab画出照度数据 )^3655mb  
    8. 在Matlab计算照度平均值 A>S2BL#=  
    9. 返回数据到FRED中 b&&'b )
