    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。 kR-5RaW  
    :U;ZBs3  
    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: `Uw^,r  
    enableservice('AutomationServer', true) Icf@uQ6  
    enableservice('AutomationServer') G#0 4h{  
    o'  DXd[y  
    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 P8s'e_t

    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: {Z|.-~W  
    1. 在FRED脚本编辑界面找到参考. >!YI7)  
    2. 找到Matlab Automation Server Type Library  /m*vY`  
    3. 将名字改为MLAPP 1<qq69x

    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。 A|@d4+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Efw/bTEg  
    1. 创建Matlab服务器。 an<tupi[E  
    2. 移动探测面对于前一聚焦面的位置。 Kc\0-3 Z  
    3. 在探测面追迹光线 $y >J=  
    4. 在探测面计算照度 R16" lG  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?z60b=f8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4 ITSDx  
    7. 用Matlab画出照度数据 #tBbvs+%  
    8. 在Matlab计算照度平均值 QTK{JZf  
    9. 返回数据到FRED中 p2 y h
