    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。 5aBAr  
    zF@o2<cD@  
    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: 3)ma\+< 6  
    enableservice('AutomationServer', true) op"$E1+  
    enableservice('AutomationServer') hY*0aZ|(  
    zVi15P$  
    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 8>7RxSF

    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: g ^!C  
    1. 在FRED脚本编辑界面找到参考. j}BHj.YuP  
    2. 找到Matlab Automation Server Type Library +&X%<S W  
    3. 将名字改为MLAPP ]Ni;w]KE

    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。 Z2Zq'3*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O<j PGU  
    1. 创建Matlab服务器。 H{?9CxYa  
    2. 移动探测面对于前一聚焦面的位置。 ~"lJ'&J}  
    3. 在探测面追迹光线 6cdMS[_SD(  
    4. 在探测面计算照度 BR v+.(S  
    5. 使用PutWorkspaceData发送照度数据到Matlab \ A%eG&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ? b[n|^wS  
    7. 用Matlab画出照度数据 2oZ9laJO  
    8. 在Matlab计算照度平均值 e8h,,:l3j  
    9. 返回数据到FRED中 T *I?9d{k
