    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。 ?|W3RK;  
    JnK<:]LcK  
    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: QH(&Cu,  
    enableservice('AutomationServer', true) ~//9Nz~;3  
    enableservice('AutomationServer') >_yL@^  
    -kLBq :M  
    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 /Ls|'2J<$  
    Bj \ x  
    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: $aJay]F  
    1. 在FRED脚本编辑界面找到参考. ff.k1%wr^  
    2. 找到Matlab Automation Server Type Library Q34u>VkdQI  
    3. 将名字改为MLAPP  d6tLC Q  
    m-Jy 4f#  
    B;=Z^$%T  
    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。 iEtR<R>=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \os"w "  
    1. 创建Matlab服务器。 r7R'beiH  
    2. 移动探测面对于前一聚焦面的位置。 4_QfM}Fyp  
    3. 在探测面追迹光线 dE,E,tv  
    4. 在探测面计算照度 !% W5@tN  
    5. 使用PutWorkspaceData发送照度数据到Matlab @B >D>B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 iU 6,B  
    7. 用Matlab画出照度数据 1DcBF@3sWG  
    8. 在Matlab计算照度平均值 X+A@//,7  
    9. 返回数据到FRED中 tUULpx.h
