    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。 O_2o/  
    0#Ug3_dfr  
    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: qlPIxd  
    enableservice('AutomationServer', true) $0$sDN6)x  
    enableservice('AutomationServer') 5D7 L)>  
    X}3?k<m  
    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 LHZsmUM(dg  
    R{A$|Ipaq  
    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: AtHkz|sl  
    1. 在FRED脚本编辑界面找到参考. ip'{@1L  
    2. 找到Matlab Automation Server Type Library *zweZG8:  
    3. 将名字改为MLAPP 4j'rbbs/  
    [Pp#r&4H  
    _/P;`@  
    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。 8o,0='U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Wy6a4oY  
    1. 创建Matlab服务器。 q$v0sTk0Y  
    2. 移动探测面对于前一聚焦面的位置。 #huh!Mn  
    3. 在探测面追迹光线 .HY,'oC.  
    4. 在探测面计算照度 4,QA {v  
    5. 使用PutWorkspaceData发送照度数据到Matlab V:5aq.o!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 P;gd!Yl<-  
    7. 用Matlab画出照度数据 a[zVC)N0  
    8. 在Matlab计算照度平均值 4<1V  
    9. 返回数据到FRED中 $d-yG553
