    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。 \B2d(=~4  
    <s-@!8*(  
    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: Nr"N\yOA/  
    enableservice('AutomationServer', true) ]|N4 #4  
        enableservice('AutomationServer') X[Ek'=}  
     y"\,%.  
    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 B Z?W>'B%$  
    DLYZsWA,  
    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: }Hz-h4Z  
    1. 在FRED脚本编辑界面找到参考. tHtV[We.:  
    2. 找到Matlab Automation Server Type Library #Q3PzDfj  
        3. 将名字改为MLAPP #tZf>zrs  
         B~>cNj<  
         $G_Q`w=jM  
    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。 mY`]33??v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ey)u7-O  
    1. 创建Matlab服务器。 }E5#X R  
    2. 移动探测面对于前一聚焦面的位置。 T;4` wB8@  
    3. 在探测面追迹光线 <s8? Z1  
    4. 在探测面计算照度 P=^#%7J/l  
    5. 使用PutWorkspaceData发送照度数据到Matlab -k&{nD|  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 (s"iC:D6U  
    7. 用Matlab画出照度数据 ,iVPcza  
    8. 在Matlab计算照度平均值 6B''9V:s  
    9. 返回数据到FRED中 _~[?> cF%
