    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_zB/(h  
    eg"!.ol  
    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: t<p4H^  
    enableservice('AutomationServer', true) >o"0QD  
    enableservice('AutomationServer') unN*L  
    ]MMXpj,9h  
    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 !1+!;R@&H>  
    :WSszak  
    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: y8di-d3_  
    1. 在FRED脚本编辑界面找到参考. gln X C  
    2. 找到Matlab Automation Server Type Library / Kj;%  
    3. 将名字改为MLAPP V\%s)kq

    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。 _#E@& z".L

    1. 创建Matlab服务器。 PtKrks|y  
    2. 移动探测面对于前一聚焦面的位置。 S#ud<=@!9  
    3. 在探测面追迹光线 hQJ-  ~  
    4. 在探测面计算照度 d[e;Fj!  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?trqe/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &K,rNH'R  
    7. 用Matlab画出照度数据 yuZh ak  
    8. 在Matlab计算照度平均值 5[$Tpn#K7
