    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。 q;qY#wD@  
    (L8z<id<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: h<f]hJ`ep  
    enableservice('AutomationServer', true) %-, -:e  
    enableservice('AutomationServer') T#G (&0J5  
    VTJ,;p_UH  
    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 1ml{oqNj

    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: dpcFS0  
    1. 在FRED脚本编辑界面找到参考. wfF0+T+IA  
    2. 找到Matlab Automation Server Type Library >_um-w#C  
    3. 将名字改为MLAPP Nm=\~LP90

    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。 g_t1(g*s

    3. 在探测面追迹光线 `}9jvR5  
    4. 在探测面计算照度 4XL]~3 c  
    5. 使用PutWorkspaceData发送照度数据到Matlab By-A1|4Cp`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d|(@#*{T]  
    7. 用Matlab画出照度数据 Qk.:b  
    8. 在Matlab计算照度平均值 1k! xG$g0
