    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。 r jn:E  
    0Md.3kY  
    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: xT&/xZLT  
    enableservice('AutomationServer', true) #Db^*  
    enableservice('AutomationServer') ugN%8N  
    *P\lzM  
    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 cPZ\iGy  
    L=;T$4+p  
    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: &I ~'2mpk  
    1. 在FRED脚本编辑界面找到参考. x_O:IK.>  
    2. 找到Matlab Automation Server Type Library rx| ,DI  
    3. 将名字改为MLAPP J[l7p6xk

    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。 z4D)Xy"/

    1. 创建Matlab服务器。 U4dfO=  
    2. 移动探测面对于前一聚焦面的位置。 /NB|N*}O)  
    3. 在探测面追迹光线 ^vh!1"T  
    4. 在探测面计算照度 xr.;B`T0\'  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9E5*%Hu_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [}Xw/@Uc;  
    7. 用Matlab画出照度数据 N:64Gko"K  
    8. 在Matlab计算照度平均值 +(Hp ".gU
