    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。 8L.Y0_x  
    ^O4.$4t|  
    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: vxK}f*d  
    enableservice('AutomationServer', true) 7 zK%CJ  
    enableservice('AutomationServer') Q+gQ"l,95  
    H<g- Bhv  
    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 b=.Ikt+y

    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: b?qtTce  
    1. 在FRED脚本编辑界面找到参考. d+Pfi)+(I  
    2. 找到Matlab Automation Server Type Library ABB4(_3E  
    3. 将名字改为MLAPP :Q"]W!kCs

    $ ^m_M.1  
    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。 nO2-fW:9]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u:NSPAD)  
    1. 创建Matlab服务器。 M+9G^o)u  
    2. 移动探测面对于前一聚焦面的位置。 8E ^yHd4Y  
    3. 在探测面追迹光线 #8QQZdC8`  
    4. 在探测面计算照度 o"J}@nF  
    5. 使用PutWorkspaceData发送照度数据到Matlab PL[7|_%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 S2h?Q $e3  
    7. 用Matlab画出照度数据 c{7!:hi`x  
    8. 在Matlab计算照度平均值 2/x+7F}w5  
    9. 返回数据到FRED中 s=#3f3
