    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。 EhW@iYL  
    B"7~[,he  
    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: i [/1AI  
    enableservice('AutomationServer', true) ; {m;CKHI  
    enableservice('AutomationServer') BAqwYWdS  
    B \V ;{:  
    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 be6`Sv"H

    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:  LWo)x  
    1. 在FRED脚本编辑界面找到参考. D<Z\6)|%I  
    2. 找到Matlab Automation Server Type Library MNfc1I_#  
    3. 将名字改为MLAPP Mt4`~`6  
    #;2kN &  
    6_EfOD9  
    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。 IFSIQ q

    1. 创建Matlab服务器。 * se),CP!s  
    2. 移动探测面对于前一聚焦面的位置。 FN0<iL  
    3. 在探测面追迹光线 *@ \LS!N  
    4. 在探测面计算照度 m7,"M~\pX  
    5. 使用PutWorkspaceData发送照度数据到Matlab o hPXwp?]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Y Odwd}M  
    7. 用Matlab画出照度数据 neWx-O  
    8. 在Matlab计算照度平均值 o>M&C X+j$
