    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。 EBS04]5ul  
    w">XI)*z  
    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: D0,U2d  
    enableservice('AutomationServer', true) ~;W]0d4,\  
    enableservice('AutomationServer') n{j14b'  
    g W'aK>*c  
    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  ^G{3x  
    c[@-&o`  
    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: -~eNC^t;W  
    1. 在FRED脚本编辑界面找到参考. j{EN %  
    2. 找到Matlab Automation Server Type Library _wp6rb:8!  
    3. 将名字改为MLAPP Px&*&^Gf[b  
    y4s]*?Wz  
    7Zp'}Om<I  
    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。 3dNOXk, #

    现在将脚本代码公布如下,此脚本执行如下几个步骤: uiDK&@RS  
    1. 创建Matlab服务器。 zghUwW|K  
    2. 移动探测面对于前一聚焦面的位置。  q%,q"WU  
    3. 在探测面追迹光线 Qjh5m5e  
    4. 在探测面计算照度 yWsV !Ub  
    5. 使用PutWorkspaceData发送照度数据到Matlab r6&f I"Yg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 D]v=/43  
    7. 用Matlab画出照度数据 "ZF:}y  
    8. 在Matlab计算照度平均值 "NSm2RU3  
    9. 返回数据到FRED中 F>E'/r*
