    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。 p/Q< VV  
    v;G/8>GRy  
    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: ?lgE9I]  
    enableservice('AutomationServer', true) 4[gbRn'  
    enableservice('AutomationServer') ^H2TSaJ;  
    )quQI)Ym  
    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 0sKo NzE

    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: ^GrSvl}v'  
    1. 在FRED脚本编辑界面找到参考. Qj1%'wWG  
    2. 找到Matlab Automation Server Type Library [tSv{  
    3. 将名字改为MLAPP j DEym&-  
    RA!m,"RM  
    8YE4ln  
    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。 zVtTv-DU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ws,?ImA  
    1. 创建Matlab服务器。 !BrZTo  
    2. 移动探测面对于前一聚焦面的位置。 1I'}Uh*  
    3. 在探测面追迹光线 G7,v:dlK   
    4. 在探测面计算照度 35AH|U7b  
    5. 使用PutWorkspaceData发送照度数据到Matlab h(}#s1Fzq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 W7~_XI  
    7. 用Matlab画出照度数据 muF&t'k  
    8. 在Matlab计算照度平均值 Y>FLc* h  
    9. 返回数据到FRED中 !,Gavt7f
