    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。 8lwM{?k$  
    ~`R1sSr"  
    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: d>!p=O`>{q  
    enableservice('AutomationServer', true) w>vH8f  
    enableservice('AutomationServer') 1[DS'S  
    RmOyGSO  
    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 rk,p!}FqL  
    9":2"<'+  
    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: V]c5 Z$Bd  
    1. 在FRED脚本编辑界面找到参考. h|p[OecG  
    2. 找到Matlab Automation Server Type Library xl2g0?  
    3. 将名字改为MLAPP t5) J;0/

    dJl^ADX[@  
    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。 gs`> C(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0JXqhc9'  
    1. 创建Matlab服务器。 cNj*E =~;  
    2. 移动探测面对于前一聚焦面的位置。 &N\[V-GP2G  
    3. 在探测面追迹光线 W-D[z#)/Y  
    4. 在探测面计算照度 e<5Y94YE  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2[up+;%Y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5AOfp2O  
    7. 用Matlab画出照度数据 w^o }E)O  
    8. 在Matlab计算照度平均值 4* M@]J "  
    9. 返回数据到FRED中 p5<2N
