    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。 JpC'(N  
    R+M=)Z  
    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: {Yj5Mj|#  
    enableservice('AutomationServer', true) ETdXk&AN  
    enableservice('AutomationServer') vFVUdxPOw  
    "tz6O0D  
    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 }csA|cC

    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: 9GD0jJEu  
    1. 在FRED脚本编辑界面找到参考. :(n<c  
    2. 找到Matlab Automation Server Type Library KNx/1 lf  
    3. 将名字改为MLAPP zuvPV{ X

    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。 hC<ROD

    3. 在探测面追迹光线 :,l7e  
    4. 在探测面计算照度 -+*h'zZ[<w  
    5. 使用PutWorkspaceData发送照度数据到Matlab Bu{Kjv  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {@InOo!4w]  
    7. 用Matlab画出照度数据 m TE(J Zt  
    8. 在Matlab计算照度平均值 9F/I",EA  
    9. 返回数据到FRED中 "\b>JV5
