    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。 #$?!P1  
    t91z<Y|  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: H2iC? cSR  
    enableservice('AutomationServer', true) U~l.%mui  
    enableservice('AutomationServer') C U 8s*  
    0%b !ARix  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 iYR`|PJi  
    }%lk$g';  
    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: [izP1A$r#Q  
    1. 在FRED脚本编辑界面找到参考. -NL=^O$G  
    2. 找到Matlab Automation Server Type Library >713H!uj  
    3. 将名字改为MLAPP pLtAusx

    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。 L_(Y[!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: yq]/r=e!k  
    1. 创建Matlab服务器。 RGC DC*\  
    2. 移动探测面对于前一聚焦面的位置。 C%T$l8$  
    3. 在探测面追迹光线 mgL{t"$c  
    4. 在探测面计算照度 hI}rW^o^  
    5. 使用PutWorkspaceData发送照度数据到Matlab F*{1, gb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h#?)H7ft  
    7. 用Matlab画出照度数据 _Y 8RP%  
    8. 在Matlab计算照度平均值 71wtO  
    9. 返回数据到FRED中 gg+!e#-X
