    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。 k\8]fh)J\7  
    Q%o:*(x[O  
    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: ~:~-AXaMT  
    enableservice('AutomationServer', true) AC;ja$A#  
    enableservice('AutomationServer') T$RVz   
    PzbLbH8A  
    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  u;R<  
    H3"90^|,@  
    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: |dcRDOTe  
    1. 在FRED脚本编辑界面找到参考. 9(g?{6v|  
    2. 找到Matlab Automation Server Type Library xPoI+,  
    3. 将名字改为MLAPP 7t &KKKV  
    #!(OTe L  
    +L D\~dcV+  
    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。 .\K0+b;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: qOAK`{b  
    1. 创建Matlab服务器。 VX0q!Q  
    2. 移动探测面对于前一聚焦面的位置。 ?UCK  
    3. 在探测面追迹光线 \6~(# y  
    4. 在探测面计算照度 e=S51q_0  
    5. 使用PutWorkspaceData发送照度数据到Matlab is @8x!c  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w-9M{Es+j  
    7. 用Matlab画出照度数据 w64/$  
    8. 在Matlab计算照度平均值 C\#E1\d  
    9. 返回数据到FRED中 Wm_:1~
