    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。 ? 8)$N  
    cOEzS  
    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]FKY  
    enableservice('AutomationServer', true) 2E}^'o  
    enableservice('AutomationServer') *gXm&/2*  
    w'Q2Czso  
    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 ;V3d"@R,  
    M;qV% k  
    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: \Rvsy;7  
    1. 在FRED脚本编辑界面找到参考. b1qli5  
    2. 找到Matlab Automation Server Type Library "Q<*H<e  
    3. 将名字改为MLAPP Yg14aKZl

    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。 t9 m],aH

    2. 移动探测面对于前一聚焦面的位置。 b(H) 8#C  
    3. 在探测面追迹光线 3$ 1 z  
    4. 在探测面计算照度 QabYkL5@  
    5. 使用PutWorkspaceData发送照度数据到Matlab *d/]-JN,K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [M6/?4\  
    7. 用Matlab画出照度数据 ? /Z hu  
    8. 在Matlab计算照度平均值 ;F<)BEXC<
