    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。 QTeFR&q8  
    6hLNJ  
    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: q%DVDq( z  
    enableservice('AutomationServer', true) Z6NJ)XQy6F  
    enableservice('AutomationServer') J &{qppN  
    >/8ru*Oc  
    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 u >81dO]H

    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: XynU/Go,  
    1. 在FRED脚本编辑界面找到参考. ~Vwk:+):  
    2. 找到Matlab Automation Server Type Library Gee~>:_Q{J  
    3. 将名字改为MLAPP "$]ls9-%n  
    nZ&T8@m  
    Mp^^!AP9  
    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。 tSI& "-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: r >E\Cco  
    1. 创建Matlab服务器。 #NW Zk.S  
    2. 移动探测面对于前一聚焦面的位置。 Akv(} !g  
    3. 在探测面追迹光线 =d}gv6v2S  
    4. 在探测面计算照度 Q@7l"8#[t  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,tcP=f dk]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 U?JiVxE^  
    7. 用Matlab画出照度数据 ]cn/(U`  
    8. 在Matlab计算照度平均值 i5.?g<.H  
    9. 返回数据到FRED中 '`9%'f)
