    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。 .@OQ$ D<  
    'A:Y&w"r  
    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: { %X2K  
    enableservice('AutomationServer', true) JnBc@qnP6  
    enableservice('AutomationServer') . i4aM;Qy  
    mk1R~4v  
    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 *GE6zGdN  
    tf6m .  
    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: hp'oiR;~w  
    1. 在FRED脚本编辑界面找到参考. '1b 1N5~  
    2. 找到Matlab Automation Server Type Library t(*n[7e  
    3. 将名字改为MLAPP 'D5J5+.z  
    $"/l*H\h

    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。 ru eaP

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u5}:[4N%I  
    1. 创建Matlab服务器。 u$aK19K/  
    2. 移动探测面对于前一聚焦面的位置。 :P_h_Tizv  
    3. 在探测面追迹光线 _j , Tc*T  
    4. 在探测面计算照度 _r3Y$^!U  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]w6 F%d  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (v/L   
    7. 用Matlab画出照度数据 x&;AY  
    8. 在Matlab计算照度平均值 vm+3!s:u  
    9. 返回数据到FRED中 (]'wQ4iQ
