    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。 "B`k  
    #1fT\aP  
    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: {*utke]}*  
    enableservice('AutomationServer', true) ;e,_F/@`  
    enableservice('AutomationServer') EB R,j_  
    .Z%y16)T  
    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 P^9y0Q

    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: l;{n" F  
    1. 在FRED脚本编辑界面找到参考. *_feD+rq  
    2. 找到Matlab Automation Server Type Library eS(hLXE!7  
    3. 将名字改为MLAPP m?3!

    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。  NGQBOV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: : :;YS9e  
    1. 创建Matlab服务器。 >s0A.7,5  
    2. 移动探测面对于前一聚焦面的位置。 Y9V%eFY5E  
    3. 在探测面追迹光线 &1nZ%J9  
    4. 在探测面计算照度 G<1)N T\u  
    5. 使用PutWorkspaceData发送照度数据到Matlab ',Y`XP"Q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^a+W!  
    7. 用Matlab画出照度数据 NTq#'O) f  
    8. 在Matlab计算照度平均值 x=-dv8N?  
    9. 返回数据到FRED中 C8ss6+k&
