    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。 DZ1.Bm0  
    R! n7g8I%  
    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: u9(42jj[$U  
    enableservice('AutomationServer', true) B873UN  
    enableservice('AutomationServer') ,c0t#KgQ.  
    ,hr v  
    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 .'.bokl/  
    zC*dJXt@  
    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: YNl".c  
    1. 在FRED脚本编辑界面找到参考. K2\)9  
    2. 找到Matlab Automation Server Type Library itE/QB  
    3. 将名字改为MLAPP Wsp c ;]&

    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。 Q"uK6ANp'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =c$x xEDD  
    1. 创建Matlab服务器。 ]NtBP  
    2. 移动探测面对于前一聚焦面的位置。 <o[3*59  
    3. 在探测面追迹光线 6nJQPa  
    4. 在探测面计算照度 +sTPTCLE  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~g%Ht# <  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 FhPCFmmUT  
    7. 用Matlab画出照度数据 @h_ bXo  
    8. 在Matlab计算照度平均值 }D?qj3?bj  
    9. 返回数据到FRED中 \rATmjsKzS
