    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。 Z]SUr`Z  
    .[:y`PCF  
    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: MP|$+yuR~  
    enableservice('AutomationServer', true) M nnVk=  
    enableservice('AutomationServer') o_sb+Vn|  
    z7s}-w,  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 "=Cjm`9~j  
    ++!'6! l  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Q"s]<MtdS  
    1. 在FRED脚本编辑界面找到参考. Gm[XnUR7V  
    2. 找到Matlab Automation Server Type Library bMB@${i}  
    3. 将名字改为MLAPP > ofWHl[-  
    cKB1o0JsYJ  
    5 )z'=  
    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。 *o=[p2d"X

    现在将脚本代码公布如下,此脚本执行如下几个步骤: wln"g,ct  
    1. 创建Matlab服务器。 y`Zn{mQ@[  
    2. 移动探测面对于前一聚焦面的位置。 l^2m7 7)  
    3. 在探测面追迹光线 >W6?!ue_  
    4. 在探测面计算照度 1Q7]1fRu  
    5. 使用PutWorkspaceData发送照度数据到Matlab GK[9Cm"v  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 MxqIB(5k  
    7. 用Matlab画出照度数据 |`pDOd  
    8. 在Matlab计算照度平均值 ZU;nXqjc  
    9. 返回数据到FRED中 _Mi*Fvj
