    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。 !=j\pu} Z  
    =Nn&$h l  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ?;!d5Xuu  
    enableservice('AutomationServer', true) |=H*" (  
    enableservice('AutomationServer') Ag1*.t|  
    f`w$KVZ1!w  
    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 M`!\$D  
    et|QW;*L  
    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: e;KZTH;  
    1. 在FRED脚本编辑界面找到参考. ^:g8mt  
    2. 找到Matlab Automation Server Type Library FSZQ2*n5  
    3. 将名字改为MLAPP |:_WdU"Q]

    jj^{^,z\  
    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。 :7&#ej6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?3bUE\p  
    1. 创建Matlab服务器。 6x%uWZa'  
    2. 移动探测面对于前一聚焦面的位置。 K)5'Jp@  
    3. 在探测面追迹光线 C'x?riJ/  
    4. 在探测面计算照度 ~IvAnwQ'  
    5. 使用PutWorkspaceData发送照度数据到Matlab z(]14250  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,H!E :k  
    7. 用Matlab画出照度数据 w'[lIEP 2$  
    8. 在Matlab计算照度平均值 Dohq@+] O  
    9. 返回数据到FRED中 5:(uD3]
