    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。 GNOC5 E$I  
    X2v'9 x  
    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: o:<3n,T  
    enableservice('AutomationServer', true) mM.&c5U  
        enableservice('AutomationServer') VIzZmd  
    F}>`3//u  
    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 ,-)1)R\.  
    mX^RSg9E}  
    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: $ cSZX#\  
    1. 在FRED脚本编辑界面找到参考. J~.kb k  
    2. 找到Matlab Automation Server Type Library Ji q[VeLe  
        3. 将名字改为MLAPP 4+Y5u4 `t  
         Cq~Ir*"  
          7I|Mq  
    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。 bAp`lmFI

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :cTi$n  
    1. 创建Matlab服务器。 T*m21<  
    2. 移动探测面对于前一聚焦面的位置。 t ,$)PV  
    3. 在探测面追迹光线 1CbC|q  
    4. 在探测面计算照度 soF^G21N  
    5. 使用PutWorkspaceData发送照度数据到Matlab k1J}9HNYR  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 2uIAnbW]M  
    7. 用Matlab画出照度数据 Q*: Ow]  
    8. 在Matlab计算照度平均值 zdCt#=QV?R  
    9. 返回数据到FRED中  t2iFd?
