    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。 eX]9m Q]E  
     5Fl  
    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: z?IY3]v*z<  
    enableservice('AutomationServer', true) [W8iM7D  
    enableservice('AutomationServer') gzJ{Gau{)  
    4u{E D(  
    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 #7cf 8y  
    8m1 3M5r  
    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{n*NxKCX!  
    1. 在FRED脚本编辑界面找到参考. A<*tn?M]  
    2. 找到Matlab Automation Server Type Library JVIcNK)  
    3. 将名字改为MLAPP 0 6G[^  
    z? b(|f\!  
    %l]rQjV-  
    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。 h>`'\qy

     +lf@O&w  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: NiJ?no  
    1. 创建Matlab服务器。 6r-<XNv)0  
    2. 移动探测面对于前一聚焦面的位置。 F6neG~Y  
    3. 在探测面追迹光线 {KQ-Ce-6  
    4. 在探测面计算照度 &&QDEDszp  
    5. 使用PutWorkspaceData发送照度数据到Matlab Af! W K=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 S92 !jp/  
    7. 用Matlab画出照度数据 #VMBn}   
    8. 在Matlab计算照度平均值  vCH v  
    9. 返回数据到FRED中 ;wYwiSVd
