    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。 (Ybc~M)z  
    )9 5&-Hs  
    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: [94A?pn[z  
    enableservice('AutomationServer', true) }L>}_NV\  
    enableservice('AutomationServer') D'ZR>@w@  
    m"<0sqD;  
    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 y!u)q3J0&  
    =LDzZ:' 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: TDs=VTd@Z  
    1. 在FRED脚本编辑界面找到参考. =21$U[  
    2. 找到Matlab Automation Server Type Library 9Iq[@v  
    3. 将名字改为MLAPP n@XI$>B  
    & V^ Z

    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。  #8MA+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Hgu$)yhlj  
    1. 创建Matlab服务器。 [^ $nt  
    2. 移动探测面对于前一聚焦面的位置。 ^.p({6H  
    3. 在探测面追迹光线 .LhIB?  
    4. 在探测面计算照度 x2=Bu#Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab NQz*P.q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 F&%@p&  
    7. 用Matlab画出照度数据 <qT[  
    8. 在Matlab计算照度平均值 N4I`6uDgD  
    9. 返回数据到FRED中 kfr' P u
