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。 D;!sH?J@+  
 Lw\u{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: ;3/}"yG<p  
enableservice('AutomationServer', true) ;JkIZ8!  
enableservice('AutomationServer') n0=]C%wr  
]Uwp\2Bc  
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。 dCoP qKy  
?1ey$SSU]  
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: z[f]mU  
1. 在FRED脚本编辑界面找到参考. i?/Q7D<P  
2. 找到Matlab Automation Server Type Library Ln# o:"E  
3. 将名字改为MLAPP 7 {92_xRL  
U:*rlA@_.  
Z+ k) N  
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。 iTinZ!Ut

现在将脚本代码公布如下,此脚本执行如下几个步骤: k)3N0]q6  
1. 创建Matlab服务器。 O H>.N"IG  
2. 移动探测面对于前一聚焦面的位置。 yc*cT%?g  
3. 在探测面追迹光线 tCrEcjT-  
4. 在探测面计算照度 'KjH|u  
5. 使用PutWorkspaceData发送照度数据到Matlab ^P9mJ:  
6. 使用PutFullMatrix发送标量场数据到Matlab中 M1eh4IVE?  
7. 用Matlab画出照度数据 0cG[<\qT  
8. 在Matlab计算照度平均值 2-'_Nwkl*  
9. 返回数据到FRED中 wxHd^b
