    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。 l|v`B6(  
    0~4Ww=#  
    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$G &~A{  
    enableservice('AutomationServer', true) ||D PIn]  
    enableservice('AutomationServer') >e>%AMzo[  
    w{mw?0  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 >e^bq/'  
    @CMEmgk~  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: xIA]5@;a  
    1. 在FRED脚本编辑界面找到参考. HA$X g j  
    2. 找到Matlab Automation Server Type Library V/`vX;%  
    3. 将名字改为MLAPP KT[ZOtu  
    $7" Y/9Y  
    /g$G G9  
    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。 zX lcu_rc

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~y{_NgMo  
    1. 创建Matlab服务器。 Jr5dw=B gw  
    2. 移动探测面对于前一聚焦面的位置。 (@->AJF1\  
    3. 在探测面追迹光线 90#* el  
    4. 在探测面计算照度 @Bds0t  
    5. 使用PutWorkspaceData发送照度数据到Matlab \HXq~Y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /k8I6  
    7. 用Matlab画出照度数据 3^[P  
    8. 在Matlab计算照度平均值 _B>'07D0  
    9. 返回数据到FRED中 wx^Det
