    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。 V!94I2%#x  
    ;=[~2*8  
    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: ^cy.iolt  
    enableservice('AutomationServer', true) w0FkKJV  
    enableservice('AutomationServer') 9M&uQccY  
    Px<*n '~}  
    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 iHB1/  
    ~3u'=u9l  
    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: IfdgMELk  
    1. 在FRED脚本编辑界面找到参考. \-?@ &' :  
    2. 找到Matlab Automation Server Type Library j>70AE3[8  
    3. 将名字改为MLAPP =(x W7Pt~  
    A=5A8B1  
    psHW(Z8G  
    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。 J^R#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ]"Qm25`Qz  
    1. 创建Matlab服务器。 ,?Bo x  
    2. 移动探测面对于前一聚焦面的位置。 9<ev]XaSl  
    3. 在探测面追迹光线 ^l(Kj3gM  
    4. 在探测面计算照度 .jfkOt?2  
    5. 使用PutWorkspaceData发送照度数据到Matlab mz~aSbb|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vQ/&iAyut  
    7. 用Matlab画出照度数据 Nd"4*l;  
    8. 在Matlab计算照度平均值 P{-f./(JD  
    9. 返回数据到FRED中 @+3@Z?!SZ
