    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。 BJE <~"  
    IYO,/ kbf  
    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: @j (jOe  
    enableservice('AutomationServer', true) 8`t%QhE2  
    enableservice('AutomationServer') PGKXzp'  
    ?c2TT Q  
    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 5oKc=iX_3  
    3k<#;(  
    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: Hj\~sR$L-  
    1. 在FRED脚本编辑界面找到参考. (FaT{W{  
    2. 找到Matlab Automation Server Type Library x-pMT3m\D#  
    3. 将名字改为MLAPP asi1c y\

    3DHm9n+/:  
    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。 m?j!0>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: t0>{0 5  
    1. 创建Matlab服务器。 `Ek!;u>  
    2. 移动探测面对于前一聚焦面的位置。 X w8i l  
    3. 在探测面追迹光线 nsT|,O  
    4. 在探测面计算照度 ;Kf|a}m-  
    5. 使用PutWorkspaceData发送照度数据到Matlab kOCxIJ!Xp=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8w&rj-  
    7. 用Matlab画出照度数据 XNU qZ-M :  
    8. 在Matlab计算照度平均值 9^='&U9sr  
    9. 返回数据到FRED中 W~%~^2g ;k
