    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。 f 6I)c$]Q  
    {qw'gJmX  
    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: sK%b16#  
    enableservice('AutomationServer', true) Vs"b  
    enableservice('AutomationServer') RJ?)O#}  
    \IQG%L{  
    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  C O6}D  
    cpk\;1&t  
    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: .gy:Pl]w  
    1. 在FRED脚本编辑界面找到参考. P.Tnq  
    2. 找到Matlab Automation Server Type Library [7><^?t V  
    3. 将名字改为MLAPP (*A@V%H  
    boiP_*|MY  
     (7X  
    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&fBX6;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #btz94/~O  
    1. 创建Matlab服务器。 o+x%q<e;c  
    2. 移动探测面对于前一聚焦面的位置。 V n_&q6Pa  
    3. 在探测面追迹光线 UovN"8W+  
    4. 在探测面计算照度 }h1BAKg  
    5. 使用PutWorkspaceData发送照度数据到Matlab fOMaTnm'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 p{oz}}  
    7. 用Matlab画出照度数据 vs8[352  
    8. 在Matlab计算照度平均值 -Jd7  
    9. 返回数据到FRED中 /'8%=$2Kw
