    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。 icIn>i<m  
    M:GpyE%  
    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: !u@P\8M}  
    enableservice('AutomationServer', true) Rx&O}>"E>l  
    enableservice('AutomationServer') `MCiybl,&P  
    X!K>.r_Dg  
    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 ""jW'%wR

    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: 1P(=0\ P>&  
    1. 在FRED脚本编辑界面找到参考. fs 2MYat  
    2. 找到Matlab Automation Server Type Library )xccs'H  
    3. 将名字改为MLAPP :MY=Q]l  
    x<M::")5!V  
    d\nXK#)Q  
    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。 -f&vH_eK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rAfz?  
    1. 创建Matlab服务器。 " Q?~LB  
    2. 移动探测面对于前一聚焦面的位置。 xws{"m,NX~  
    3. 在探测面追迹光线 :\P@c(c{^C  
    4. 在探测面计算照度 OyVP_Yx,V  
    5. 使用PutWorkspaceData发送照度数据到Matlab #jW-&a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i7-~"g  
    7. 用Matlab画出照度数据 OU/}cu  
    8. 在Matlab计算照度平均值 =~hb&  
    9. 返回数据到FRED中 H^*AaA9-
