    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。 'Ud| Ex@A9  
    k#)Ad*t  
    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: =-jD~rN4;P  
    enableservice('AutomationServer', true) J7&DR^.Sw  
    enableservice('AutomationServer') kv?|'DN  
    "="O >  
    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 H\G{3.T.9  
    83iCL;GS=  
    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: *l>0t]5YH  
    1. 在FRED脚本编辑界面找到参考. Z(Q2Ue;}&  
    2. 找到Matlab Automation Server Type Library JW+*d`8Z[  
    3. 将名字改为MLAPP _ PWj(});

    {aj/HFLNY  
    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。 z&+ zl6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $H2GbZ-I  
    1. 创建Matlab服务器。 |. C1|J'Z  
    2. 移动探测面对于前一聚焦面的位置。 w:ULi3  
    3. 在探测面追迹光线 FJS'G^  
    4. 在探测面计算照度 LAs7>hM  
    5. 使用PutWorkspaceData发送照度数据到Matlab Dpqt;8"2L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 }Uw#f@Wh  
    7. 用Matlab画出照度数据 zV.pol  
    8. 在Matlab计算照度平均值  [aW =  
    9. 返回数据到FRED中 QT!5l`
