    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。 pTCD1)  
    rWTaCU^qV  
    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: ] `$6=) _X  
    enableservice('AutomationServer', true) 9i\RdJv.  
    enableservice('AutomationServer') $`|h F[tv  
    ~^2w)-N  
    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 f6Y?),`  
    n+8YTjd  
    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: M2Nh3ijr  
    1. 在FRED脚本编辑界面找到参考. %unn{92)  
    2. 找到Matlab Automation Server Type Library jlBsm'M<m  
    3. 将名字改为MLAPP 9 Zos;  
    nX!%9x$3  
    rN&fFI  
    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。 6]1RxrAV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SD^::bH  
    1. 创建Matlab服务器。 k9 r49lb  
    2. 移动探测面对于前一聚焦面的位置。 -9om,U`t  
    3. 在探测面追迹光线 >GIQT ?O6  
    4. 在探测面计算照度 Yb5U^OjyJ  
    5. 使用PutWorkspaceData发送照度数据到Matlab lf( +]k30  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ._0$#J S[  
    7. 用Matlab画出照度数据 "o- -MBq4  
    8. 在Matlab计算照度平均值 96\FJHt Z  
    9. 返回数据到FRED中 7**zb"#y
