    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。 x0u?*5-t  
    yZ;k@t_WRD  
    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: KkdG.c'  
    enableservice('AutomationServer', true) MdVCD^B  
    enableservice('AutomationServer') vn0cKz@  
    hi {2h04  
    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 ZSF=

    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: ol?z<53X]  
    1. 在FRED脚本编辑界面找到参考. l&6U|q`  
    2. 找到Matlab Automation Server Type Library (:.Q\!aZ1  
    3. 将名字改为MLAPP r,u<y_YW

    >9o,S3  
    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。 mJ8{lXq3!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O)R7t3t  
    1. 创建Matlab服务器。 4Vu'r?  
    2. 移动探测面对于前一聚焦面的位置。 'a;ini  
    3. 在探测面追迹光线 gx!*O<|e4  
    4. 在探测面计算照度 1u"R=D9p,=  
    5. 使用PutWorkspaceData发送照度数据到Matlab >a&?AP #  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #<a_: m)@  
    7. 用Matlab画出照度数据 ^%n124  
    8. 在Matlab计算照度平均值 )l+XDI  
    9. 返回数据到FRED中 1DEO3p
