    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。 +g*k*e>l  
    j6:7AH|!)2  
    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: *A}WP_ZQ  
    enableservice('AutomationServer', true) v1G"3fy9  
    enableservice('AutomationServer') W#F Q,+0)  
    r`'y?Bra;  
    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 "9y( }  
    C}}/)BYi  
    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: VDF)zA1V  
    1. 在FRED脚本编辑界面找到参考. jQs>`P-CM  
    2. 找到Matlab Automation Server Type Library X$?3U!  
    3. 将名字改为MLAPP @\P4/+"9

    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。 oDB`iiBXQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T3%C%BcX  
    1. 创建Matlab服务器。 |9K<-yD  
    2. 移动探测面对于前一聚焦面的位置。 0$.m_0H  
    3. 在探测面追迹光线 <X7\z  
    4. 在探测面计算照度 Of}|ib^t  
    5. 使用PutWorkspaceData发送照度数据到Matlab m}j:nk  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _Q(g(p&  
    7. 用Matlab画出照度数据 %D}H|*IPu  
    8. 在Matlab计算照度平均值 El2e~l9  
    9. 返回数据到FRED中 T? ,P*l
