    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。 RH _b  
    oST)E5X;7  
    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: R8u8jG(4  
    enableservice('AutomationServer', true) ;nW;M 4{  
    enableservice('AutomationServer') hp(MKfhH  
    )D6 i {I0  
    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 stUv!   
    D})/2O p   
    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: QK0]9   
    1. 在FRED脚本编辑界面找到参考. Oy=0Hsh@x  
    2. 找到Matlab Automation Server Type Library &&P9T/Zks  
    3. 将名字改为MLAPP A>upT'  
    8w:mL^6x  
    Dbj?l;'1  
    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。 Tc||96%2^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: X;6;v]  
    1. 创建Matlab服务器。 #TR!x,Hc  
    2. 移动探测面对于前一聚焦面的位置。 B F gxa#De  
    3. 在探测面追迹光线 U!o  
    4. 在探测面计算照度 !h7:rv/  
    5. 使用PutWorkspaceData发送照度数据到Matlab TsoxS/MI"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 U= f9b]Y  
    7. 用Matlab画出照度数据 <_|@ ~^u  
    8. 在Matlab计算照度平均值 >h#juO"  
    9. 返回数据到FRED中 V )oXJL
