    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。 1gL8$.B?  
    bwT"$Ee  
    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: EywZIw?mjX  
    enableservice('AutomationServer', true) o^N%;d1%E  
    enableservice('AutomationServer') /}[zA@  
    Y}*Ctdrl  
    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 %9cqJ]S  
    Lp~c  
    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: {=UKTk/t8  
    1. 在FRED脚本编辑界面找到参考. s-y'<(ll  
    2. 找到Matlab Automation Server Type Library WodF -bE  
    3. 将名字改为MLAPP ((n5';|N  
    QZ_nQ3K  
     #=>kw^5  
    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。 eDvXU_yA

    现在将脚本代码公布如下,此脚本执行如下几个步骤: t,UW&iLK  
    1. 创建Matlab服务器。 CAcOWwDm  
    2. 移动探测面对于前一聚焦面的位置。 a^(S!I  
    3. 在探测面追迹光线 b'i%B9yU:%  
    4. 在探测面计算照度 u_$6LEp-  
    5. 使用PutWorkspaceData发送照度数据到Matlab D}3cW2!9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {5?!`<fF  
    7. 用Matlab画出照度数据 c|8KT  
    8. 在Matlab计算照度平均值 ~0:$G?fz  
    9. 返回数据到FRED中 0^_)OsFA
