    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。 k5)e7Lb(  
    EYU3Pl%  
    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: %|3NCyJ*7  
    enableservice('AutomationServer', true) \E,Fe:/g  
    enableservice('AutomationServer') 0^3@>> ^  
    ?N@p~ *x  
    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 Z"a]AsG/Q#

    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: ~[ x}  
    1. 在FRED脚本编辑界面找到参考. 1 =9 Kwd  
    2. 找到Matlab Automation Server Type Library a\v@^4   
    3. 将名字改为MLAPP i)+2? <]

    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。 8}Su7v1

    1. 创建Matlab服务器。 BW%"]J  
    2. 移动探测面对于前一聚焦面的位置。 [&p^h  
    3. 在探测面追迹光线 L51uC ,QF  
    4. 在探测面计算照度 0x8aKq\'  
    5. 使用PutWorkspaceData发送照度数据到Matlab "K-2y ^Dl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @|J+ f5O  
    7. 用Matlab画出照度数据 ue#Y h  
    8. 在Matlab计算照度平均值 a |+q:g0M  
    9. 返回数据到FRED中 r2 o-/$
