    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。 |@4' <4t  
    f._ua>v,f  
    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: 1p=]hC  
    enableservice('AutomationServer', true) =B@2#W#  
    enableservice('AutomationServer') $6SW;d+>n  
    +52{-a,>  
    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 ~b8]H|<'Y  
    pZy~1L  
    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: W7nw6;7=  
    1. 在FRED脚本编辑界面找到参考. %1+4_g9  
    2. 找到Matlab Automation Server Type Library pYf-S?Y/V  
    3. 将名字改为MLAPP Qzw;i8n{  
    qlPT Ll  
    Qt<&WB fn  
    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。 "=MeM)K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8KzkB;=n  
    1. 创建Matlab服务器。 * r7rZFS  
    2. 移动探测面对于前一聚焦面的位置。 /cP"h!P}~~  
    3. 在探测面追迹光线 1bwOm hkS  
    4. 在探测面计算照度 X!EP$!  
    5. 使用PutWorkspaceData发送照度数据到Matlab T]~ xj4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 QoT;WM Z  
    7. 用Matlab画出照度数据 LZxNAua  
    8. 在Matlab计算照度平均值 tc_3sC7jN  
    9. 返回数据到FRED中 AFwdJte9e
