    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。 g3n'aD@'x  
    lLq<xf  
    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: '[|+aJ  
    enableservice('AutomationServer', true) h/eR  
    enableservice('AutomationServer') 6dH }]~a  
    Zd^6ulx  
    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 s1Ok|31|  
    `cz2DR-"  
    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: Xm2\0=v5;  
    1. 在FRED脚本编辑界面找到参考. ha@L94Lq  
    2. 找到Matlab Automation Server Type Library ^{$FI`P  
    3. 将名字改为MLAPP M6 9 w-  
    l} ^3fQXI  
    =.<@`1  
    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。 zIC;7 5#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TlL^7f}  
    1. 创建Matlab服务器。 @53k8  
    2. 移动探测面对于前一聚焦面的位置。 WtQ8X|\`  
    3. 在探测面追迹光线 Jk|Q`h  
    4. 在探测面计算照度 [%~ :@m  
    5. 使用PutWorkspaceData发送照度数据到Matlab {u{@ jp  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %V &n*3  
    7. 用Matlab画出照度数据 ~I/@i  
    8. 在Matlab计算照度平均值 _EnwME {@  
    9. 返回数据到FRED中 L$'[5"ma ;
