    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。 8Ac)'2t;U  
    l^ZI* z7N  
    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: |f~@8|MQP+  
    enableservice('AutomationServer', true) bM8If"  
        enableservice('AutomationServer') 2gO2jJlv  
    G!K]W:m  
    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 3"o"fl

    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: O3TQixE  
    1. 在FRED脚本编辑界面找到参考. PH"n{lW.T  
    2. 找到Matlab Automation Server Type Library GKN%Tv:D_  
        3. 将名字改为MLAPP fRg`UI4w}  
         Q+4Xs.#  
         j'9"cE5_  
    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。 b Q]/?cCYV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O'Js}  
    1. 创建Matlab服务器。 ^i:`ZfA#  
    2. 移动探测面对于前一聚焦面的位置。 1V8-^  
    3. 在探测面追迹光线 ()~pY!)1/  
    4. 在探测面计算照度 K~@Mg1R  
    5. 使用PutWorkspaceData发送照度数据到Matlab iD<(b`S  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 +$oF]OO  
    7. 用Matlab画出照度数据 &f&z_WU  
    8. 在Matlab计算照度平均值 p.LFVFPT  
    9. 返回数据到FRED中 @|Rrf*J?%
