    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。 '11hIu=:  
    .1M>KRSr,  
    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: y+h=x4t  
    enableservice('AutomationServer', true) EatDT*!  
    enableservice('AutomationServer') \/zS@fz  
    l>q.BG  
    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 t F( mD=[  
    W0hLh<Go  
    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: a)b@en;v  
    1. 在FRED脚本编辑界面找到参考. |V]E8Qt  
    2. 找到Matlab Automation Server Type Library  $nWmoe)  
    3. 将名字改为MLAPP ]B[Qdn  
    _: x$"i  
    =B2=UF  
    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。 ZrBxEf$f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &2^V<(19  
    1. 创建Matlab服务器。 ;rbn/6  
    2. 移动探测面对于前一聚焦面的位置。 y0^FTSQ|  
    3. 在探测面追迹光线 I}x*AM 7+  
    4. 在探测面计算照度 Ho|n\7$  
    5. 使用PutWorkspaceData发送照度数据到Matlab "m5ZZG#R`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]T`qPIf;yJ  
    7. 用Matlab画出照度数据 A}# Mrb  
    8. 在Matlab计算照度平均值 p6*D^-  
    9. 返回数据到FRED中 (reD
