    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。 aV`4M VWOz  
    |pk1pV |  
    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: Mo`7YS-Y  
    enableservice('AutomationServer', true) 6+HpN"?e  
    enableservice('AutomationServer') {'P7D4w  
    %Z?2 .)  
    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 >(+g:p  
    _ Js & _d  
    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: }ybveZxv5A  
    1. 在FRED脚本编辑界面找到参考. xe5|pBT  
    2. 找到Matlab Automation Server Type Library 8d.5D&  
    3. 将名字改为MLAPP Wi]Mp7b  
    $8#zPJR&  
    Ht#5;c2/  
    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。 qD:3;85

    现在将脚本代码公布如下,此脚本执行如下几个步骤: < wV?B9j  
    1. 创建Matlab服务器。 afY~Y?PJ<  
    2. 移动探测面对于前一聚焦面的位置。 g2p/#\D\J  
    3. 在探测面追迹光线 `[x`#irD  
    4. 在探测面计算照度 f%ude@E3  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8+m;zvDSU  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <}x_F)E[t  
    7. 用Matlab画出照度数据 1B+uv0lA  
    8. 在Matlab计算照度平均值 V~p/P  
    9. 返回数据到FRED中 _IiTB
