    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。 }k0B   
    s x2\  
    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: x"~gulcz  
    enableservice('AutomationServer', true) a 9!.e rM  
        enableservice('AutomationServer') !bBx'  
    ! i8'gq'q  
    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 Ey&gZ$|&  
    `Y,<[ Lnr  
    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: BnU3oP  
    1. 在FRED脚本编辑界面找到参考. X\1.,]O >  
    2. 找到Matlab Automation Server Type Library c,Yd#nokC  
        3. 将名字改为MLAPP h3Y|0-D  
         MI,kKi  
         ki ?ETC  
    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。 <"Yx}5n.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: j>)yV@g/  
    1. 创建Matlab服务器。 _n+ 5{\z  
    2. 移动探测面对于前一聚焦面的位置。 "H|hN  
    3. 在探测面追迹光线 jg3T1ROL  
    4. 在探测面计算照度 6Ao{Aej|  
    5. 使用PutWorkspaceData发送照度数据到Matlab O^r,H,3S  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 !Q=xIS  
    7. 用Matlab画出照度数据 HFW8x9Cc  
    8. 在Matlab计算照度平均值 64l(ru<  
    9. 返回数据到FRED中 A Eo
