    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。 adh=Kp e!w  
    ln7{c #lE  
    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: E ?(  
    enableservice('AutomationServer', true) NamBJ\2E1[  
    enableservice('AutomationServer') 5tg  
    =N`"%T@=  
    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 2l#Ogn`k  
    BF2,E<^A  
    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: rLNo7i  
    1. 在FRED脚本编辑界面找到参考. udDhJ?  
    2. 找到Matlab Automation Server Type Library 15_OtK  
    3. 将名字改为MLAPP mvI[=e*  
    Au$|@  
    mxhO: .l  
    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。 2/qP:3)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: RV5X0  
    1. 创建Matlab服务器。 E)m{m$Hb  
    2. 移动探测面对于前一聚焦面的位置。 7</&=lly  
    3. 在探测面追迹光线 7_taqcj  
    4. 在探测面计算照度 h8oG5|Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab !CROc}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l [?o du4  
    7. 用Matlab画出照度数据 j0!Z 20  
    8. 在Matlab计算照度平均值 [Z|R-{"  
    9. 返回数据到FRED中 HcA;'L?Dw
