    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。 ]i:_^z)R  
    {44#<A<  
    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: ) w1`<7L  
    enableservice('AutomationServer', true) ;TC"n!ew  
    enableservice('AutomationServer') }1#prQ0F  
    bk=ee7E7>  
    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 U!\~LKfA

    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: sW,JnR  
    1. 在FRED脚本编辑界面找到参考. W>j@E|m$  
    2. 找到Matlab Automation Server Type Library sx n{uRF  
    3. 将名字改为MLAPP #I"s{*

    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。 'N3)>!Y:8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @GWJq 3e  
    1. 创建Matlab服务器。 AGGT] 58|  
    2. 移动探测面对于前一聚焦面的位置。 3c=>;g  
    3. 在探测面追迹光线 +P=Ikbx AO  
    4. 在探测面计算照度 QnA~,z/ .w  
    5. 使用PutWorkspaceData发送照度数据到Matlab yu>o7ie+;Y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !T#EkMM  
    7. 用Matlab画出照度数据 = inp>L  
    8. 在Matlab计算照度平均值 +'$5Jtz  
    9. 返回数据到FRED中 #:NY9.\o
