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。 !?K#f?x<?  
"wxyY^"  
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: 'HL.W](  
enableservice('AutomationServer', true) `84,R!  
enableservice('AutomationServer') ],'"iVh  
3,Iu!KB  
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。 wzY{ii

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: ^5k~ 7F.  
1. 在FRED脚本编辑界面找到参考. L_M(Lj  
2. 找到Matlab Automation Server Type Library y3P4]sq  
3. 将名字改为MLAPP B f.- 5

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。 B& 5Md.h

现在将脚本代码公布如下,此脚本执行如下几个步骤: QM7B FS;  
1. 创建Matlab服务器。 oS<*\!&D  
2. 移动探测面对于前一聚焦面的位置。 D&DbxTi  
3. 在探测面追迹光线 L}K8cB  
4. 在探测面计算照度 p]7IoO -@  
5. 使用PutWorkspaceData发送照度数据到Matlab ( yB]$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 . \8"f]~  
7. 用Matlab画出照度数据 Lx| 0G $  
8. 在Matlab计算照度平均值 vLGnLpt  
9. 返回数据到FRED中 *De'4r 2
