    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。 /Y`u4G()  
    7t3ps  
    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: 2r"J"C  
    enableservice('AutomationServer', true) KL\hV .6  
    enableservice('AutomationServer') :[J'B4>9  
    ?p'DgL{  
    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 _Q9I W  
    T&nIH[}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: K"/3/`T  
    1. 在FRED脚本编辑界面找到参考. [J8;V|v  
    2. 找到Matlab Automation Server Type Library 61W[  
    3. 将名字改为MLAPP T9\G,;VQ7/

    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。 z'9U.v'M)

    1. 创建Matlab服务器。 t Uk)S  
    2. 移动探测面对于前一聚焦面的位置。 ECk* H  
    3. 在探测面追迹光线 n.7-$1  
    4. 在探测面计算照度 -oT3`d3  
    5. 使用PutWorkspaceData发送照度数据到Matlab o/hj~;(]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LUzn7FZk  
    7. 用Matlab画出照度数据 %j/}e>$"Nk  
    8. 在Matlab计算照度平均值 WXQ+`OH7  
    9. 返回数据到FRED中 6E{(_i
