    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。 x$SxGc~4gb  
    w'r?)WW$  
    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: NMy+=GZu^  
    enableservice('AutomationServer', true) Xn%ty@8  
    enableservice('AutomationServer') ELvP<Ny}  
    qH=<8Iu  
    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 &s{" Vc9]

    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: ~K 2.T7=  
    1. 在FRED脚本编辑界面找到参考. :lfUVa{HN  
    2. 找到Matlab Automation Server Type Library RE<s$B$[  
    3. 将名字改为MLAPP kq4ii`zi8  
    u3k{s  
    f, iHM  
    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。 W'xJh0o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6Trtulm  
    1. 创建Matlab服务器。 fxOa(mt  
    2. 移动探测面对于前一聚焦面的位置。 ^o8o  
    3. 在探测面追迹光线 x|=]Xxco  
    4. 在探测面计算照度 |19zjhl  
    5. 使用PutWorkspaceData发送照度数据到Matlab dI%#cf1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \i.Yhl:O  
    7. 用Matlab画出照度数据 ?= R C?K  
    8. 在Matlab计算照度平均值 nYb{?{_ca8  
    9. 返回数据到FRED中 q(XO_1W0V
