    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。 DjiI*HLNR  
    6JeAXj1g+  
    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: {d0 rUHP  
    enableservice('AutomationServer', true) i5_l//]  
    enableservice('AutomationServer') h#dfhcU>  
    6OJhF7\0&  
    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 pc QkJ F

    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: D(Q]ddUi'  
    1. 在FRED脚本编辑界面找到参考. DGw*BN%`  
    2. 找到Matlab Automation Server Type Library '*Tt$0#o  
    3. 将名字改为MLAPP .]a`-Ofn

    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。 ;>fM?ae5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: sPl3JP&s  
    1. 创建Matlab服务器。 >5TXLOYZ  
    2. 移动探测面对于前一聚焦面的位置。 YN7O Qqa  
    3. 在探测面追迹光线 " YOl6n  
    4. 在探测面计算照度 %h;1}SFl0  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9l|*E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f)V6VNW.3  
    7. 用Matlab画出照度数据 }AiF 7N0  
    8. 在Matlab计算照度平均值 k'sPA_|  
    9. 返回数据到FRED中 .$Yp~
