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。 `KpFH.k.K  
V1SqX:;b&  
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: 7G5y)Qb  
enableservice('AutomationServer', true) y?pD(u  
enableservice('AutomationServer') #bT8QbJ(  
;} lT  
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。 |h&<_9  
(j' {~FB  
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: E6Q]A~  
1. 在FRED脚本编辑界面找到参考. "z^(dF|  
2. 找到Matlab Automation Server Type Library ~|r~NO 7[  
3. 将名字改为MLAPP .u1X+P7  
ZFS7{:  
T><{ze  
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。 v6s\Z\v)Q`

现在将脚本代码公布如下,此脚本执行如下几个步骤: QsiJ%O Q  
1. 创建Matlab服务器。 ugYw <  
2. 移动探测面对于前一聚焦面的位置。 X8/Tl \c  
3. 在探测面追迹光线 OAv>g pw  
4. 在探测面计算照度 8|O=/m^]  
5. 使用PutWorkspaceData发送照度数据到Matlab $<B +K  
6. 使用PutFullMatrix发送标量场数据到Matlab中 'p%= <0vrr  
7. 用Matlab画出照度数据 d%0+i/p  
8. 在Matlab计算照度平均值 Q48+O?&  
9. 返回数据到FRED中 q-3]jHChh
