FRED如何调用Matlab

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。 EN>a^B+!  
EcR[b@YI  
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: a[=B?Bd  
enableservice('AutomationServer', true) ]RVme^=  
enableservice('AutomationServer') {j[*:l0Ui  
~2NT Xp  
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。 21?>rezJ  
=xH>,-8}  
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: 2C_I3S ~U  
1. 在FRED脚本编辑界面找到参考. :W'.SRD  
2. 找到Matlab Automation Server Type Library s,laJf  
3. 将名字改为MLAPP #LYx;[D6  
3=Xvl 58k  
wC<FF2T  
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。 ~ayU\4B

现在将脚本代码公布如下,此脚本执行如下几个步骤: mL@7,GD  
1. 创建Matlab服务器。 Pj^Ccd'>=  
2. 移动探测面对于前一聚焦面的位置。 Kna@K$6{w=  
3. 在探测面追迹光线 (elkk#  
4. 在探测面计算照度 Vx n-  
5. 使用PutWorkspaceData发送照度数据到Matlab &3~R-$P  
6. 使用PutFullMatrix发送标量场数据到Matlab中 'Te'wh=Y  
7. 用Matlab画出照度数据 >BMtR0  
8. 在Matlab计算照度平均值 lzz68cT  
9. 返回数据到FRED中 [}l 1`>
