    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。 jV^Dj  
    p&=F:-  
    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: dA<PQKm  
    enableservice('AutomationServer', true) /#?lG`'1  
    enableservice('AutomationServer') rJJI<{$  
    3Q^@ !hu  
    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 z<~gv"  
    ?U]/4]  
    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: Do}mCv  
    1. 在FRED脚本编辑界面找到参考. y 1fl=i  
    2. 找到Matlab Automation Server Type Library T!o 4k  
    3. 将名字改为MLAPP { U a19~'>  
    ': Gk~   
    =4 &/Pr  
    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。 _s./^B_w!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: KYY~ YP  
    1. 创建Matlab服务器。 Pg%OFhA  
    2. 移动探测面对于前一聚焦面的位置。 8Z>ZjNG  
    3. 在探测面追迹光线 H"8+[.xBh  
    4. 在探测面计算照度 4.bL>Y>c  
    5. 使用PutWorkspaceData发送照度数据到Matlab Y418k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =)C}u6  
    7. 用Matlab画出照度数据 3`4g*wO  
    8. 在Matlab计算照度平均值  }5^j08  
    9. 返回数据到FRED中 hQrO8T?2
