    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。 ,cS_687o  
    wKpb%3  
    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: /kw;q{>?o  
    enableservice('AutomationServer', true) p(="73  
    enableservice('AutomationServer') k;JDVRL  
    xCWS  
    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 p{v*/<.;

    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: bJ9*z~z)e  
    1. 在FRED脚本编辑界面找到参考. ?7lW@U0  
    2. 找到Matlab Automation Server Type Library `'5vkO>  
    3. 将名字改为MLAPP x![.C,O

    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。 WI*CuJU<zJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <}'=@a  
    1. 创建Matlab服务器。 Z]tQmV8e  
    2. 移动探测面对于前一聚焦面的位置。 p_]b=3wt~  
    3. 在探测面追迹光线 9LBZMQ  
    4. 在探测面计算照度 D@.qdRc3  
    5. 使用PutWorkspaceData发送照度数据到Matlab SYf1dbc..u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~#P]NWW%.  
    7. 用Matlab画出照度数据 OAiv3"p  
    8. 在Matlab计算照度平均值 gs/ocu  
    9. 返回数据到FRED中 zG/? wP"
