    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。 wEBtre7  
    g&{gD^9)4  
    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: Vxp$#3 ;S  
    enableservice('AutomationServer', true) XC*uz  
    enableservice('AutomationServer') 7bA4P*  
    )w Z49>Y  
    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 oP+kAV#]  
    N8,EI^W8Z  
    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: S9 $o  
    1. 在FRED脚本编辑界面找到参考. ->#y(}  
    2. 找到Matlab Automation Server Type Library ;%BhhmR)[  
    3. 将名字改为MLAPP -Pqi1pj]

    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。 ,AdusM

    1. 创建Matlab服务器。 !T<z'zZU

    3. 在探测面追迹光线 ybD{4&ZE  
    4. 在探测面计算照度 IW5*9)N?  
    5. 使用PutWorkspaceData发送照度数据到Matlab -s9Y(>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i!CKA}",  
    7. 用Matlab画出照度数据 >v^2^$^u  
    8. 在Matlab计算照度平均值 .'l.7t
