    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。 `T*U]/zQ  
    AH7L.L+$M  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ,a|@d} U  
    enableservice('AutomationServer', true) 9pWy"h$H  
    enableservice('AutomationServer') ,1n >U?5  
    ~d>%,?zz  
    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 Z%o7f6P0IX

    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: H! r &aP  
    1. 在FRED脚本编辑界面找到参考. .,2V5D-${  
    2. 找到Matlab Automation Server Type Library SDJH;c0   
    3. 将名字改为MLAPP ~9pM%N V

    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。 ]o.vB}WsY

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Ayx^Wp*s  
    1. 创建Matlab服务器。 R zR?&J  
    2. 移动探测面对于前一聚焦面的位置。 -<f/\U  
    3. 在探测面追迹光线 H>7dND 2;  
    4. 在探测面计算照度 SQ(apc}N4  
    5. 使用PutWorkspaceData发送照度数据到Matlab <)m%*9{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Dk)}|GJ()"  
    7. 用Matlab画出照度数据 B:oF;~d/,  
    8. 在Matlab计算照度平均值 N{a kg90  
    9. 返回数据到FRED中 vS; '}N
