    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。 hh"=|c  
    @|J+ f5O  
    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: B$%7U><'  
    enableservice('AutomationServer', true) GHo=)NTjy  
    enableservice('AutomationServer') '}T6e1#JV  
    KRh95B GU  
    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 3QzHQU  
    C~a- R#  
    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: x'wT%/hp  
    1. 在FRED脚本编辑界面找到参考. \!,@pe_  
    2. 找到Matlab Automation Server Type Library c`h/x>fa  
    3. 将名字改为MLAPP (@1*-4l  
    l/w<R  
    Mlr}v^"G  
    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。 xYCX}bksh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4`#3p@-  
    1. 创建Matlab服务器。 RAW(lZ(  
    2. 移动探测面对于前一聚焦面的位置。 f*^)0Po  
    3. 在探测面追迹光线 yp:_W@  
    4. 在探测面计算照度 ?Em*yc@WD  
    5. 使用PutWorkspaceData发送照度数据到Matlab *PJg~F%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4#BoS9d2I<  
    7. 用Matlab画出照度数据 =+j>?Yi  
    8. 在Matlab计算照度平均值 `* =Tf  
    9. 返回数据到FRED中 YaDr.?
