    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。 ke!  
    ^ >&#F[aT  
    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: ',xUU{5?  
    enableservice('AutomationServer', true) @"BhKUoV$K  
    enableservice('AutomationServer') 3!\h'5{  
    c-5AI{%bl6  
    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 z?Ok'LX

    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: M]p-<R\  
    1. 在FRED脚本编辑界面找到参考. i-w$-2w  
    2. 找到Matlab Automation Server Type Library RD"-(T  
    3. 将名字改为MLAPP 9od*N$

    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。 XVqkw@Ia4!

    3. 在探测面追迹光线 |hw.nY]J  
    4. 在探测面计算照度 3~bB2APk  
    5. 使用PutWorkspaceData发送照度数据到Matlab yyljyE  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 FG[rH]   
    7. 用Matlab画出照度数据 qzJ<9H  
    8. 在Matlab计算照度平均值 KpYezdPF)
