    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。 H(k-jAO,  
    %~A$cc  
    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: yJ!x`RD),w  
    enableservice('AutomationServer', true) *)4 `"D  
    enableservice('AutomationServer') :k*3?*'K  
    n:d7 Tv1Z8  
    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 zBd)E21H  
    K4>nBvZ?v  
    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: .qjdi`v  
    1. 在FRED脚本编辑界面找到参考. V)g{ Ew]:  
    2. 找到Matlab Automation Server Type Library rAZsVnk?  
    3. 将名字改为MLAPP :Z'q1kW@"

    &z"sT*3  
    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。 6EeK5XLf,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -w#Hy>E  
    1. 创建Matlab服务器。 PC3-X['[  
    2. 移动探测面对于前一聚焦面的位置。 hd E?%A  
    3. 在探测面追迹光线 CF?TW  
    4. 在探测面计算照度 jLLZZPBK  
    5. 使用PutWorkspaceData发送照度数据到Matlab kbF+aS  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3S_H hvB  
    7. 用Matlab画出照度数据 5QoU&Hv  
    8. 在Matlab计算照度平均值 _g#v*7o2@  
    9. 返回数据到FRED中 qIIl,!&}A
