    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。 b9#m m  
    ;@4sd%L8V  
    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: 5M.Red.L  
    enableservice('AutomationServer', true) 5L3{w+V  
    enableservice('AutomationServer') yxY h?ka  
    TrQm]9@  
    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 y#e ?iE@  
    M:(&n@e  
    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: CjV7q y  
    1. 在FRED脚本编辑界面找到参考. kQ[Jo%YT?E  
    2. 找到Matlab Automation Server Type Library ==`Pb  
    3. 将名字改为MLAPP #G~wE*VR$

    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。 B!iFmkCy

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  +Lhe,  
    1. 创建Matlab服务器。 J@gm@ jLc  
    2. 移动探测面对于前一聚焦面的位置。 1VGpq-4*j  
    3. 在探测面追迹光线 8=pv/o  
    4. 在探测面计算照度 +K&?)?/=  
    5. 使用PutWorkspaceData发送照度数据到Matlab lJlhl7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $$\V 2%v  
    7. 用Matlab画出照度数据 OOfy Gvs  
    8. 在Matlab计算照度平均值 }pK v.  
    9. 返回数据到FRED中 WV@X@]U
