FRED案例-FRED如何调用Matlab

ai jGz<  
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。 j& iL5J;  
n E}<e:  
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: Jav2A6a  
enableservice('AutomationServer', true) *P R_Y=v%  
    enableservice('AutomationServer') <-:@} |br  
#S%Y; ilq  
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。 *X l<aNNx  
a@y5JxFAy  
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: _G[I2]  
1. 在FRED脚本编辑界面找到参考. =l4\4td9p  
2. 找到Matlab Automation Server Type Library ioNa~F&  
    3. 将名字改为MLAPP xY'qm8V  
     ,&&M|,NQ&s  
     nH>V Da  
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。 tNuCxb-

现在将脚本代码公布如下,此脚本执行如下几个步骤: ,r 2VP\hLh  
1. 创建Matlab服务器。 D5!K<G?-K  
2. 移动探测面对于前一聚焦面的位置。 fj-pNl6Gf  
3. 在探测面追迹光线 iSr`fQw#  
4. 在探测面计算照度 4m~7 ~-h  
5. 使用PutWorkspaceData发送照度数据到Matlab aaz"`,7_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bV$8 >[`  
7. 用Matlab画出照度数据 Rw}2*5#y  
8. 在Matlab计算照度平均值 >mFX^t_,  
9. 返回数据到FRED中 B >u,)
