    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/d8_(0  
    AWZ4h,as{  
    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: @M*5q# s  
    enableservice('AutomationServer', true) ]VVx2ERs  
    enableservice('AutomationServer') .>5E 4^$%  
    >wV2` 6  
    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 ,=6;dT  
    CwF=@:*d  
    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: ]xJ2;{JWsO  
    1. 在FRED脚本编辑界面找到参考. \n0Gr\:  
    2. 找到Matlab Automation Server Type Library r^d:Po  
    3. 将名字改为MLAPP ~\R+p~>

    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。 )=h+5Z>E1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n\scOM)3  
    1. 创建Matlab服务器。 k1^&;}/f:  
    2. 移动探测面对于前一聚焦面的位置。 9&4z4@on  
    3. 在探测面追迹光线 G{s q|1  
    4. 在探测面计算照度 O ~bzTn  
    5. 使用PutWorkspaceData发送照度数据到Matlab &ZPyZj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J16(d+  
    7. 用Matlab画出照度数据 r^"pLzAx  
    8. 在Matlab计算照度平均值 -[lOf  
    9. 返回数据到FRED中 z!9w Lo^r
