    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。 d*l2x[8}g-  
    C'a#.LM  
    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: C;']FmK]  
    enableservice('AutomationServer', true) V:2{LR<R8  
    enableservice('AutomationServer') K$5mDScoJ  
    "6>+IF  
    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 :Q"p!,X=-  
    0 D&-BAzi  
    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: uVa`2]NV r  
    1. 在FRED脚本编辑界面找到参考. JwdvY]  
    2. 找到Matlab Automation Server Type Library 6)_h'v<|M  
    3. 将名字改为MLAPP 64t:  
    a$$aM2.2  
    w6|l ~.$=  
    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。 4c@_u8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: R[}fr36>/  
    1. 创建Matlab服务器。 G x{G}9  
    2. 移动探测面对于前一聚焦面的位置。 6\xfoy|j  
    3. 在探测面追迹光线 OXF/4Oe  
    4. 在探测面计算照度 t]8nRZ1  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~{ l @  
    6. 使用PutFullMatrix发送标量场数据到Matlab中   9EWw  
    7. 用Matlab画出照度数据 =" pNE#  
    8. 在Matlab计算照度平均值  BF /4  
    9. 返回数据到FRED中 )3)x/WM
