    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。 A.m#wY8  
    E~]8>U?V  
    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: 3!&lio+<  
    enableservice('AutomationServer', true) &GcWv+p  
        enableservice('AutomationServer') 7Xm7{`jH  
    Q4r)TR,  
    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 $;Lb|~  
    :BG/]7>|V  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: orCD?vlh  
    1. 在FRED脚本编辑界面找到参考. u^SXg dj  
    2. 找到Matlab Automation Server Type Library K~OfC  
        3. 将名字改为MLAPP ,Khhu%$  
         $A)i}M;uK  
         Ce}wgKzr  
    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=um t<&D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4;W eB   
    1. 创建Matlab服务器。 'WkDp a  
    2. 移动探测面对于前一聚焦面的位置。 EAp6IhW{  
    3. 在探测面追迹光线  FqAW><  
    4. 在探测面计算照度 Q^4j  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ks:~Z9r}  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 mw";l$Aq}  
    7. 用Matlab画出照度数据 #~%tdmGuL  
    8. 在Matlab计算照度平均值 VYI%U'9Q  
    9. 返回数据到FRED中 X6%w6%su5
