    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。 / Sp+MB9  
    -> <_J4  
    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: zR5D)`Ph   
    enableservice('AutomationServer', true) #Io#OG<7b  
    enableservice('AutomationServer') "Dy&`  
    ]_-$  
    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 A"P1 B]

    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: ( /N`Wu  
    1. 在FRED脚本编辑界面找到参考. h?CNChRJs  
    2. 找到Matlab Automation Server Type Library ?j OpW1  
    3. 将名字改为MLAPP Y#N'bvE|%  
    `[ne<F?e  
    v=W%|iZ  
    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。 .^v7LF]Q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :Z+(H+lyZ  
    1. 创建Matlab服务器。 e%f8|3<6  
    2. 移动探测面对于前一聚焦面的位置。 km3-Hp1  
    3. 在探测面追迹光线 xr?r3Y~^e  
    4. 在探测面计算照度 CiMN J  
    5. 使用PutWorkspaceData发送照度数据到Matlab =|G PSRQ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4<O[d  
    7. 用Matlab画出照度数据 A&t}s #3  
    8. 在Matlab计算照度平均值 3Y r   
    9. 返回数据到FRED中 xt-;7
