    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。 kSqMI'89  
    *edhJUT  
    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: \avgXndI  
    enableservice('AutomationServer', true) pTcN8E&Unz  
    enableservice('AutomationServer') \4hB1-  
    :W}M$5|  
    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 /80RO:'7

    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: 1NU@k6UHl  
    1. 在FRED脚本编辑界面找到参考. }C{wGK+o[  
    2. 找到Matlab Automation Server Type Library 7,D6RP(b  
    3. 将名字改为MLAPP }FAO.

    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。 ujoJ6UOG

    2. 移动探测面对于前一聚焦面的位置。 :J;*]o:  
    3. 在探测面追迹光线 =7%c*O <  
    4. 在探测面计算照度 Xp_G9I,+  
    5. 使用PutWorkspaceData发送照度数据到Matlab LLW\1 cxi  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 t8z=R6zX  
    7. 用Matlab画出照度数据 L=-v>YL+  
    8. 在Matlab计算照度平均值 $n9Bp'<
