    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。 )R+26wZ|n*  
    ;2&ym)`  
    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: oe4r_EkYwW  
    enableservice('AutomationServer', true) B$\,l.h E  
    enableservice('AutomationServer') Q>%{Dn\?  
    p;x3gc;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 h1_9Xp~N  
    :`Z'vRj  
    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: G/)]aGr  
    1. 在FRED脚本编辑界面找到参考. e`7dRnx&0  
    2. 找到Matlab Automation Server Type Library tCVaRP8eC+  
    3. 将名字改为MLAPP pXE'5IIN  
    ,UveH` n-  
     BH<jnQ  
    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。 `mt x+C

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n N_Ylw  
    1. 创建Matlab服务器。 N!Q~?/!d  
    2. 移动探测面对于前一聚焦面的位置。 c %f'rj  
    3. 在探测面追迹光线 l&2pUv=  
    4. 在探测面计算照度 _!K@( dl  
    5. 使用PutWorkspaceData发送照度数据到Matlab ir?Y>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 S9;:)  
    7. 用Matlab画出照度数据 e.>>al  
    8. 在Matlab计算照度平均值 + lNAog  
    9. 返回数据到FRED中 d1{%z\u a
