    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。 zdem}kBIe  
    W8`6O2  
    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: _fgsHx>l7  
    enableservice('AutomationServer', true) ~c&sr5E  
    enableservice('AutomationServer') =M:Po0?0E  
    6|Dtx5 "r  
    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 [,st: Y  
    OS%[SHs  
    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: JkR%o #>5  
    1. 在FRED脚本编辑界面找到参考. V O1   
    2. 找到Matlab Automation Server Type Library @Wd (>*"zw  
    3. 将名字改为MLAPP ox<6qW

    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。 XU<owk

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `B&E?x  
    1. 创建Matlab服务器。 > mCH!ey

    3. 在探测面追迹光线 VxOWv8}|  
    4. 在探测面计算照度 ekfa"X_  
    5. 使用PutWorkspaceData发送照度数据到Matlab BGVnL}0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #N`MzmwS  
    7. 用Matlab画出照度数据 KN@ [hb7%
