    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。 iXUWIgr  
    msA' 5>  
    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: 0%;N9\  
    enableservice('AutomationServer', true) ,h%D4EVx  
    enableservice('AutomationServer') #Acon7R p  
    N `,7FI}  
    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 qy7hkq.uX

    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: V]l&{hl,  
    1. 在FRED脚本编辑界面找到参考. Ph(]?MG\_  
    2. 找到Matlab Automation Server Type Library 7>nhIp))  
    3. 将名字改为MLAPP S+.21,  
    ;,v!7   
    M(n<Iu4^_  
    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。 nuf@}W>y

    1. 创建Matlab服务器。 2x-'>i_|g  
    2. 移动探测面对于前一聚焦面的位置。 6V'wQqJ  
    3. 在探测面追迹光线 /[\6oa  
    4. 在探测面计算照度 33=Mm/<m$P  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~mN g[]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?60>'Xj j  
    7. 用Matlab画出照度数据 _v1bTg"?  
    8. 在Matlab计算照度平均值 (\Rwf}gyR  
    9. 返回数据到FRED中 X4d Xm>*?=
