    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。 H83Gx;  
    ! };OL Q  
    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: B;k3YOg  
    enableservice('AutomationServer', true) d<x7* OW)  
    enableservice('AutomationServer') '{e9Vh<x  
    M|HW$8V3_2  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 &Nzq/~uqP  
    V5]}b[X  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: +0{$J\s  
    1. 在FRED脚本编辑界面找到参考. ~ 9 F rlj  
    2. 找到Matlab Automation Server Type Library k PuY[~i%  
    3. 将名字改为MLAPP R&lJ& SgC

    _zuaImJ0o  
    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。 c/K:`XP~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &?(<6v7  
    1. 创建Matlab服务器。 %MA o<,ha  
    2. 移动探测面对于前一聚焦面的位置。 :TPT]q d@  
    3. 在探测面追迹光线 FR bmeq3c  
    4. 在探测面计算照度 CtEpS<*c  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;7;=)/-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]npsclvJ  
    7. 用Matlab画出照度数据 E:_m6 m  
    8. 在Matlab计算照度平均值 MXVQ90  
    9. 返回数据到FRED中 xZMQ+OW2i
