    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。 3!9 Z=- tD  
    |^n3{m  
    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: AHh#Fx+K  
    enableservice('AutomationServer', true) r#876.JK  
    enableservice('AutomationServer') Fe=8O ^\  
    ; 2`sN   
    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 =yi OJyx  
    Mhpdaos  
    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: }6m?d!m  
    1. 在FRED脚本编辑界面找到参考. C 0C0GqN,  
    2. 找到Matlab Automation Server Type Library I*)VZW  
    3. 将名字改为MLAPP >l1 r,/\\  
    =]>%t]  
    }p3b#fAr  
    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。 I<\ '%

    D,;\F,p  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: m2bDHQ+  
    1. 创建Matlab服务器。 L4' [XcY  
    2. 移动探测面对于前一聚焦面的位置。 yyl#{Nl@t  
    3. 在探测面追迹光线 'imU `zeo  
    4. 在探测面计算照度 7!4V >O8@  
    5. 使用PutWorkspaceData发送照度数据到Matlab #a~"K|' G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 pa/9F[  
    7. 用Matlab画出照度数据 aq>?vti1D  
    8. 在Matlab计算照度平均值 :h5J r8  
    9. 返回数据到FRED中 GrI&?=S^
