    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。 )4j#gHN\  
    @L`t/OD  
    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: 3dXyKi  
    enableservice('AutomationServer', true) B;^7Yu0,  
    enableservice('AutomationServer') gCd9"n-e  
    GMFp,Df  
    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 Nhs]U`s(g  
    R:11w#m7w  
    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: -B R&b2  
    1. 在FRED脚本编辑界面找到参考. ^/c&Ud  
    2. 找到Matlab Automation Server Type Library dw'%1g.113  
    3. 将名字改为MLAPP w+P bT6;  
    *Bc= gl$  
    e%"L79Of6)  
    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。 P*G&pitT

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "{|9Yis=

    2. 移动探测面对于前一聚焦面的位置。 aM~M@wS  
    3. 在探测面追迹光线 BB9Z?}  
    4. 在探测面计算照度 B\9ymhx;g%  
    5. 使用PutWorkspaceData发送照度数据到Matlab $KKrl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 A:>G:X5t  
    7. 用Matlab画出照度数据 ~,.Agx  
    8. 在Matlab计算照度平均值 aHS.U^2
