    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。 y~pJ|E  
    xYCX}bksh  
    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: ^gD%#3>X  
    enableservice('AutomationServer', true) A1(=7ZKz  
    enableservice('AutomationServer') |lhVk\X  
    v(2|n}qY  
    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 h_:|H8t;w

    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: C) "|sG  
    1. 在FRED脚本编辑界面找到参考. _P*<T6\J>  
    2. 找到Matlab Automation Server Type Library )Vb_0n=^  
    3. 将名字改为MLAPP '@<aS?@!t  
    D#n^U `\if  
    S<V__Sv  
    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。 @dj 2#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }{Ncww!iN  
    1. 创建Matlab服务器。 *n=NBkq%/!  
    2. 移动探测面对于前一聚焦面的位置。 r{gJ[%  
    3. 在探测面追迹光线 c~+;P(>  
    4. 在探测面计算照度 .Z"p'v  
    5. 使用PutWorkspaceData发送照度数据到Matlab yprf `D>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 EK6fd#J?1  
    7. 用Matlab画出照度数据 ;h"?h*}m!\  
    8. 在Matlab计算照度平均值 6n.W5 1g(s  
    9. 返回数据到FRED中 N3Jfp3_b@
