    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。 7G+E+A5o&  
    -#Ys67,4N  
    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: k`((6  
    enableservice('AutomationServer', true) 2Krh&  
    enableservice('AutomationServer') xj[v$HP  
    LzQOzl@z  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 K (,MtY*  
    ,m Nd#  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: JT! Cb$!  
    1. 在FRED脚本编辑界面找到参考. I {%Y0S  
    2. 找到Matlab Automation Server Type Library 60G(jO14  
    3. 将名字改为MLAPP \iRmGvT

    L0)w~F ?m  
    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。 /Un\P

    现在将脚本代码公布如下,此脚本执行如下几个步骤: A*~BkvPr  
    1. 创建Matlab服务器。 5\Rg%Ezl  
    2. 移动探测面对于前一聚焦面的位置。 pr[V*C/  
    3. 在探测面追迹光线 |'``pq/}_  
    4. 在探测面计算照度 "/y SHB[  
    5. 使用PutWorkspaceData发送照度数据到Matlab P(.XB`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ..R JHa6B  
    7. 用Matlab画出照度数据 3Rhoul[S  
    8. 在Matlab计算照度平均值 [Z2{S-)UM  
    9. 返回数据到FRED中 ,A5}HRW%
