    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:7X=t =  
    VbQ9o  
    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: t 1gH9  
    enableservice('AutomationServer', true) [+dOgyK  
    enableservice('AutomationServer') ozv:$>v@"  
    f7NK0kuA  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Q%:#xG5AmE  
    46^LPC"x  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:  lt%bGjk  
    1. 在FRED脚本编辑界面找到参考. l;_zXN   
    2. 找到Matlab Automation Server Type Library fS2 ^$"B|  
    3. 将名字改为MLAPP OY$P8y3MY

    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。 ,I# X[^/

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rWk4)+Tk  
    1. 创建Matlab服务器。 O :P%gz4  
    2. 移动探测面对于前一聚焦面的位置。 mNUc g{ +/  
    3. 在探测面追迹光线 K& / rzs-  
    4. 在探测面计算照度 Ip_S8 ;;  
    5. 使用PutWorkspaceData发送照度数据到Matlab B]jI^( P  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3e~X`K1Q<  
    7. 用Matlab画出照度数据 k\,01Y^  
    8. 在Matlab计算照度平均值 V$e\84<  
    9. 返回数据到FRED中 'Y`.0T[&
