    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。 )%TmAaj9d  
    a?1Wq  
    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: ~N4m1s"  
    enableservice('AutomationServer', true) &]Tmxh(  
    enableservice('AutomationServer') 0-gAyiKx?  
    5P bW[  
    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 UKGPtKE<

    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: F|8 &  
    1. 在FRED脚本编辑界面找到参考. jXJyc'm7  
    2. 找到Matlab Automation Server Type Library u8^lB7!e/  
    3. 将名字改为MLAPP T{ "(\X$  
    A/(a`"mK|'  
    )J |6-C  
    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。 Z+SRXKQ

    1. 创建Matlab服务器。 \8tsDG(1 '  
    2. 移动探测面对于前一聚焦面的位置。 +ZYn? #IQ  
    3. 在探测面追迹光线 ]e3Ax(i)  
    4. 在探测面计算照度 =4!mAo}  
    5. 使用PutWorkspaceData发送照度数据到Matlab KvS G;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 gw(z1L5 n  
    7. 用Matlab画出照度数据 'w/hw'F6  
    8. 在Matlab计算照度平均值 y`Fw-!'o  
    9. 返回数据到FRED中 M|-)GvR$J
