    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。 JXUnhjB,B  
    w~afQA>  
    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: 17tph;  
    enableservice('AutomationServer', true) #s{>v$F  
    enableservice('AutomationServer') ]|<PV5SY3.  
    9Gfm?.O5  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ?t$sju(\  
    HWT0oh]  
    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: aDb@u3X@  
    1. 在FRED脚本编辑界面找到参考. ePa:_?(  
    2. 找到Matlab Automation Server Type Library P5* :r3>  
    3. 将名字改为MLAPP 4,tMaQ  
    %h=)>5-T  
    ZD/>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。 7)O?jc

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V^QKn+/  
    1. 创建Matlab服务器。 J5)e 7  
    2. 移动探测面对于前一聚焦面的位置。 )|@b GEk  
    3. 在探测面追迹光线 cR}}NF  
    4. 在探测面计算照度 L~x3}o$-o  
    5. 使用PutWorkspaceData发送照度数据到Matlab LG'JQGl5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^W9[PE#F  
    7. 用Matlab画出照度数据 gP/[=:  
    8. 在Matlab计算照度平均值 <Q/^[  
    9. 返回数据到FRED中 s0H_Y'
