    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。 l@);U%\pS  
    6:5K?Yo  
    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: nL 5tHz:e  
    enableservice('AutomationServer', true) 9rEBq&  
    enableservice('AutomationServer') ~ *&\5rPb  
    `n$Ak5f  
    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 sqKx?r72

    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: Et3]n$  
    1. 在FRED脚本编辑界面找到参考. [rx9gOOa&  
    2. 找到Matlab Automation Server Type Library _V$'nz#>e  
    3. 将名字改为MLAPP 7Bj,{9^aJ  
    Z8E<^<|  
    vK!`#W`X  
    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。 E !!,JnU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @bg9 }Z%\h  
    1. 创建Matlab服务器。 ko@ej^  
    2. 移动探测面对于前一聚焦面的位置。 d<-f:}^k0  
    3. 在探测面追迹光线 akvi^]x  
    4. 在探测面计算照度 g`pq*D  
    5. 使用PutWorkspaceData发送照度数据到Matlab h,{Q%sqO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mI8EeMa{  
    7. 用Matlab画出照度数据 8$NVVw]2,  
    8. 在Matlab计算照度平均值 OD)X7PU  
    9. 返回数据到FRED中 LhO\a
