    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。 KOx#LGz  
    {eEWfMKIn  
    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: AUde_ 1hi  
    enableservice('AutomationServer', true) |GQ$UB  
    enableservice('AutomationServer') !ei20@  
    M3 u8NRd5|  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 QB,ad   
    X)OP316yx  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: *XO KH+_u  
    1. 在FRED脚本编辑界面找到参考. -RQQ|:O$  
    2. 找到Matlab Automation Server Type Library #U D  
    3. 将名字改为MLAPP ?/MXcI(  
    )d u{ZWr  
    );DIrA  
    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。 B31-<w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pw yl,A  
    1. 创建Matlab服务器。 .G~5F- 8'  
    2. 移动探测面对于前一聚焦面的位置。 @I6A9do  
    3. 在探测面追迹光线 3uG5b8?  
    4. 在探测面计算照度 *+4iBpyiB  
    5. 使用PutWorkspaceData发送照度数据到Matlab F|`B2Gr  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \Pmk`^T  
    7. 用Matlab画出照度数据 ^X%4@,AE  
    8. 在Matlab计算照度平均值 'a?.X _t  
    9. 返回数据到FRED中 >C&<dO#i
