    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。 *jps}uk<  
    8jE6zS }m  
    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: V(%L}0[]  
    enableservice('AutomationServer', true) <MlRy%3Z  
    enableservice('AutomationServer') 2sJj -3J  
    AiT&:'<UT  
    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 pm-SDp>s

    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: )vFJx[a<n`  
    1. 在FRED脚本编辑界面找到参考. n_Ht{2I  
    2. 找到Matlab Automation Server Type Library \# .@*?fk  
    3. 将名字改为MLAPP A d0dg2Gw

    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。 idLysxN

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8:%=@p>$  
    1. 创建Matlab服务器。 ZI  q!ee  
    2. 移动探测面对于前一聚焦面的位置。 g7*ii X  
    3. 在探测面追迹光线 km; M!}D  
    4. 在探测面计算照度 >9o(84AxIH  
    5. 使用PutWorkspaceData发送照度数据到Matlab paUlp7x  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "#4p#dM0e  
    7. 用Matlab画出照度数据 un4q,Ac~0  
    8. 在Matlab计算照度平均值 e>-a\g  
    9. 返回数据到FRED中 D@V1}/$UoN
