    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。 6{1=3.CL  
    D^US2B  
    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: I@/ G#3Zr  
    enableservice('AutomationServer', true) C:5- h(#  
    enableservice('AutomationServer') qfE0J;e   
    /[FDiJH2  
    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 i:0v6d

    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: J~]@#=,v  
    1. 在FRED脚本编辑界面找到参考. =N\; ?eF(  
    2. 找到Matlab Automation Server Type Library 1?FG3X 5  
    3. 将名字改为MLAPP jL"V0M]c  
    -GPJ,S V>  
    iiIns.V  
    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。 :QGo -,6-

    1. 创建Matlab服务器。 EOrui:.B)  
    2. 移动探测面对于前一聚焦面的位置。 S=!WFKcJR  
    3. 在探测面追迹光线 }]o8}$&(  
    4. 在探测面计算照度 ]wU/yc)e  
    5. 使用PutWorkspaceData发送照度数据到Matlab $It mYj.m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ZPG,o5`%  
    7. 用Matlab画出照度数据 P>X[}  
    8. 在Matlab计算照度平均值 ?IHt T3'Rt  
    9. 返回数据到FRED中 c.IUqin
