    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。 s^YTI\L \  
    aT:AxYn8  
    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: uO@3vY',n  
    enableservice('AutomationServer', true) Secq^#]8  
    enableservice('AutomationServer') ^qGA!_  
    15KV} ){  
    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 M*|VLOo=v  
    1i/::4=  
    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: TT2cOw  
    1. 在FRED脚本编辑界面找到参考. J4v0O="  
    2. 找到Matlab Automation Server Type Library $.Q>M]xH  
    3. 将名字改为MLAPP WAB0e~e:|Q  
    M ?xpwqu\  
    (y~laW!  
    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。 =v4r M0m,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {(z(NgXG/  
    1. 创建Matlab服务器。  S2&9# 6  
    2. 移动探测面对于前一聚焦面的位置。 >*= =wlOB  
    3. 在探测面追迹光线 +rsl( 08FY  
    4. 在探测面计算照度 {[,Wn:  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8VuZ,!WH#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 o"#TZB+k  
    7. 用Matlab画出照度数据 ZEj!jWP2m  
    8. 在Matlab计算照度平均值 8pk#sJ51  
    9. 返回数据到FRED中 8wX+ZL: 9
