    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。 .a*$WGb  
    PS6`o  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: J~q+G  
    enableservice('AutomationServer', true) 919g5f`  
        enableservice('AutomationServer') l'QR2r7&.  
    [Jo TWouNU  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 <Z' hZ  
    OX4D'  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: sFK<:ka  
    1. 在FRED脚本编辑界面找到参考. n^N]iw{G  
    2. 找到Matlab Automation Server Type Library Br5Io=/wg  
        3. 将名字改为MLAPP `Ny8u")=  
         M;qL)vf  
         : qRT9n$  
    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。 l{9h8]^

    2. 移动探测面对于前一聚焦面的位置。 Kdu\`c-lB  
    3. 在探测面追迹光线 yipD5,TC  
    4. 在探测面计算照度 S:/RYT"  
    5. 使用PutWorkspaceData发送照度数据到Matlab Y)}%SP>,  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 "Q{~Bj~  
    7. 用Matlab画出照度数据 `Xdxg\|  
    8. 在Matlab计算照度平均值 A@(h!Cq
