    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。 z{ 8!3>:E  
    qr*/}F6  
    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: \n5,!,A  
    enableservice('AutomationServer', true) px*MOHq K  
    enableservice('AutomationServer') @'QBrE  
    |7argk+  
    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 @RC_Ie=#)

    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: GZ1>]HB>r^  
    1. 在FRED脚本编辑界面找到参考. l!b#v`  
    2. 找到Matlab Automation Server Type Library 1~+w7Ar =(  
    3. 将名字改为MLAPP hE;  
    ]T$~a8  
    ReY K5J=O  
    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。 8ViDh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: uW]n3)7<I  
    1. 创建Matlab服务器。 :KQ<rLd  
    2. 移动探测面对于前一聚焦面的位置。 0@ -LV:jU  
    3. 在探测面追迹光线 o,29C7Ii  
    4. 在探测面计算照度 0P|WoC X  
    5. 使用PutWorkspaceData发送照度数据到Matlab Mqq7;w@(J  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #pIb:/2a_  
    7. 用Matlab画出照度数据 c9Cp!.#*E  
    8. 在Matlab计算照度平均值 gw H6r3=y(  
    9. 返回数据到FRED中 \t}!Dr+yN
