    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。 D-4f >  
    H=Y{rq@  
    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: lJis~JLd`  
    enableservice('AutomationServer', true) ZGYr$C~  
    enableservice('AutomationServer') EodQ*{l  
    2L} SJUk*  
    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 i-6F:\;  
    2|}+T6_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: -U/c\-~fU  
    1. 在FRED脚本编辑界面找到参考. h >s!K9  
    2. 找到Matlab Automation Server Type Library WzF !6n!h  
    3. 将名字改为MLAPP al9t^

    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。 Gq }U|Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ML8<4o  
    1. 创建Matlab服务器。 T3pmVl  
    2. 移动探测面对于前一聚焦面的位置。 m/y2WlcRx  
    3. 在探测面追迹光线 [3--(#R\}?  
    4. 在探测面计算照度 ek}a}.3 {  
    5. 使用PutWorkspaceData发送照度数据到Matlab R5 9S@MsuD  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \8 h;K>=h  
    7. 用Matlab画出照度数据 KjE+QUa  
    8. 在Matlab计算照度平均值 J_v$YwE  
    9. 返回数据到FRED中 )_i qAqkS
