    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。 #+5pgD2C  
    M|qteo  
    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: U($dx.`v#  
    enableservice('AutomationServer', true) @I/]D6 ~"  
    enableservice('AutomationServer') 3]UUG  
    k |%B?\m  
    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 k"]dK,,  
    #Av.iAs  
    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: 5v}8org  
    1. 在FRED脚本编辑界面找到参考. ^8Q62  
    2. 找到Matlab Automation Server Type Library 1ilBz9x*!  
    3. 将名字改为MLAPP 3G~@H>j

    w1"nffhO  
    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。 yA(K=?sq

    3. 在探测面追迹光线 )5U[o0td  
    4. 在探测面计算照度 78OIUNm`  
    5. 使用PutWorkspaceData发送照度数据到Matlab _DNHc*  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G\r?f&  
    7. 用Matlab画出照度数据 +g]yA3  
    8. 在Matlab计算照度平均值 mPP`xL?T
