    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。 -2z,cj&E{  
    .2/,XwIr  
    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: a.1`\ $]d  
    enableservice('AutomationServer', true) 4"z;CGE7  
    enableservice('AutomationServer') iW":DOdi_  
    mUiOD$rO  
    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 V3 qT<}y|

    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: ;i/"$K  
    1. 在FRED脚本编辑界面找到参考. { q})kO  
    2. 找到Matlab Automation Server Type Library aDXpkG0E  
    3. 将名字改为MLAPP >b3@>W  
    Q^vGj</u  
    ` v>/  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 .$UTH@;7

    1. 创建Matlab服务器。 P`z7@9*j  
    2. 移动探测面对于前一聚焦面的位置。 X1O65DMr`g  
    3. 在探测面追迹光线 V;P1nL4L  
    4. 在探测面计算照度 W3"vTZJF  
    5. 使用PutWorkspaceData发送照度数据到Matlab }WA<=9e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /(y4V  
    7. 用Matlab画出照度数据 L,O>6~9:^1  
    8. 在Matlab计算照度平均值 Ia=&.,xub  
    9. 返回数据到FRED中 i_|h{JK)
