    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。 Fi+8|/5  
    ^^,cnDlm  
    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: d?:KEi-<7  
    enableservice('AutomationServer', true) `PY=B$?{4  
        enableservice('AutomationServer') :1asY:)vNP  
    .A6D&-&z  
    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 RN^<bt{_U  
    M.FY4~  
    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: Cv[_N%3[  
    1. 在FRED脚本编辑界面找到参考. R?{f:,3R  
    2. 找到Matlab Automation Server Type Library '/="bSF  
        3. 将名字改为MLAPP l bs0i  
         Es<& 6  
         uB=DC'lkg  
    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。 1;v,rs M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: o|G'vMph  
    1. 创建Matlab服务器。 p=!12t  
    2. 移动探测面对于前一聚焦面的位置。 #| pn,/  
    3. 在探测面追迹光线 Ztl?*zL  
    4. 在探测面计算照度 :6gRoMb]  
    5. 使用PutWorkspaceData发送照度数据到Matlab v6U Gr4  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Q~R%|Q{&  
    7. 用Matlab画出照度数据 %1mIngW=g  
    8. 在Matlab计算照度平均值 _V`F_C\\#  
    9. 返回数据到FRED中 XX7zm_>+
