    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。 EX_& wep@1  
    #Z :r  
    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: yrw!b\  
    enableservice('AutomationServer', true) Jp- hFD  
    enableservice('AutomationServer') o=ex{g(3  
    6k2~j j1d  
    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 iYnt:C  
    v;S JgZK  
    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: a'BBp6  
    1. 在FRED脚本编辑界面找到参考. U|=y&a2Rb  
    2. 找到Matlab Automation Server Type Library ;XT$rtuX  
    3. 将名字改为MLAPP X`&E,;bIb  
    n" sGI  
    bTj,5,8 i  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 5zU$_M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F>OYZOC]  
    1. 创建Matlab服务器。 Liofv4![  
    2. 移动探测面对于前一聚焦面的位置。 pS0T>r  
    3. 在探测面追迹光线 i> ;G4  
    4. 在探测面计算照度 YpJzRm{Ra  
    5. 使用PutWorkspaceData发送照度数据到Matlab Uu ,Re  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AWw'pgTQX  
    7. 用Matlab画出照度数据 {PZe!EQ  
    8. 在Matlab计算照度平均值 t1kD5^  
    9. 返回数据到FRED中 lG2){){j
