    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。 J6Z[c*W  
    XNYA\%:5S  
    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: 3B&A)&pEO  
    enableservice('AutomationServer', true) bWswF<y-  
        enableservice('AutomationServer') &uNec( c  
    T`bYidA  
    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 *4cuWkQ,

    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: g&Vhu8kNIA  
    1. 在FRED脚本编辑界面找到参考. ]at$ohS  
    2. 找到Matlab Automation Server Type Library uk):z$ x  
        3. 将名字改为MLAPP Vm[Rp, "

    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。 uBm"Xkxe|w

    2. 移动探测面对于前一聚焦面的位置。 L< F8+a7i  
    3. 在探测面追迹光线 DSrU7#  
    4. 在探测面计算照度  U4!bW  
    5. 使用PutWorkspaceData发送照度数据到Matlab RM2Ik_IH[l  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 \((iR>^|  
    7. 用Matlab画出照度数据 clE9I<1v  
    8. 在Matlab计算照度平均值 Ni_H1G
