    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。 Iq0[Kd0.j  
    0$qK: ze  
    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: 9xN`  
    enableservice('AutomationServer', true) 6`h}#@ (  
    enableservice('AutomationServer') l\/uXP?  
    \wKnX]xGf  
    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 B:>>D/O

    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: mz2v2ma  
    1. 在FRED脚本编辑界面找到参考. O:]e4r,'  
    2. 找到Matlab Automation Server Type Library S`Xx('!/|  
    3. 将名字改为MLAPP b$eN]L   
    ^, &'  
    Ak dx1h,  
    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。 c(kYCVc

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c Cx_tGR"  
    1. 创建Matlab服务器。 *`_ 2uBz  
    2. 移动探测面对于前一聚焦面的位置。 S l`F`  
    3. 在探测面追迹光线 :caXQ)  
    4. 在探测面计算照度 k|^YYi= xF  
    5. 使用PutWorkspaceData发送照度数据到Matlab O@>ZYA%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [w*]\x'S  
    7. 用Matlab画出照度数据 ~c=F$M^"c  
    8. 在Matlab计算照度平均值 v@d]*TG  
    9. 返回数据到FRED中 35H.ZXQp-
