    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。 ~i>'3j0@k  
    blaXAqe  
    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: &rc r>-  
    enableservice('AutomationServer', true)  {~w!  
    enableservice('AutomationServer') &iy7It  
    +]hc!s8  
    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 (@O,U  
    [:A">eYI  
    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: 4r7a ZDVA\  
    1. 在FRED脚本编辑界面找到参考. +|4olK$[  
    2. 找到Matlab Automation Server Type Library \oP  
    3. 将名字改为MLAPP avXBCvP+h  
    ax 2#XSCO  
    >F/E,U ]  
    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。 l[nf"'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SF[Z]|0gs  
    1. 创建Matlab服务器。 *2YWvGc  
    2. 移动探测面对于前一聚焦面的位置。 Lr`Gyl62  
    3. 在探测面追迹光线 ZMK1V)ohn  
    4. 在探测面计算照度 S@4bpnhK  
    5. 使用PutWorkspaceData发送照度数据到Matlab -, $:^4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 KT<N ;[;  
    7. 用Matlab画出照度数据 i}))6   
    8. 在Matlab计算照度平均值 *r6v9  
    9. 返回数据到FRED中 160BgFM
