    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。 :5_394v  
    qkBCI,X_Y  
    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: `&i\q=u+  
    enableservice('AutomationServer', true) d$:LUxM#  
    enableservice('AutomationServer') U3BhoD#f\  
    IC+!XZqS  
    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 k1~? }+<e  
    !7Nz_d~n  
    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: a([8r- zP  
    1. 在FRED脚本编辑界面找到参考. Zu|qN*N4  
    2. 找到Matlab Automation Server Type Library |jb,sd[=S  
    3. 将名字改为MLAPP q,>4#J[2;s

    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。 ,$Xhwr

    现在将脚本代码公布如下,此脚本执行如下几个步骤: gjn1ha"h%.  
    1. 创建Matlab服务器。 Kiq[PK  
    2. 移动探测面对于前一聚焦面的位置。 '3fN2[(  
    3. 在探测面追迹光线 UdcrX`^.  
    4. 在探测面计算照度 ]nq/y AF%  
    5. 使用PutWorkspaceData发送照度数据到Matlab k(M(]y_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J$i.^|hE/  
    7. 用Matlab画出照度数据 F$jfPy-f  
    8. 在Matlab计算照度平均值 Fb6d1I^wR  
    9. 返回数据到FRED中 .+&M,% x
