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。 ]i8K )/  
lqF{Y<l  
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: XG<^j}H{}  
enableservice('AutomationServer', true) 0`h[|FYV  
enableservice('AutomationServer') d?v#gW  
0 u,=OvU  
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。 #E{aN?_  
2^ ^;Q:  
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: >tr_Ypfv,c  
1. 在FRED脚本编辑界面找到参考. YRG+I GX  
2. 找到Matlab Automation Server Type Library .sbU-_ij@U  
3. 将名字改为MLAPP ngsax1xO  
xGk@BA=0<  
>BrxJw#M  
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。 _-%ay

现在将脚本代码公布如下,此脚本执行如下几个步骤: q)G*"  
1. 创建Matlab服务器。 Te[[xhTyw  
2. 移动探测面对于前一聚焦面的位置。 ~H@':Mms.h  
3. 在探测面追迹光线 7v?tSob:b  
4. 在探测面计算照度 S4qh8c  
5. 使用PutWorkspaceData发送照度数据到Matlab bjm`u3 A  
6. 使用PutFullMatrix发送标量场数据到Matlab中 >, 234ab=d  
7. 用Matlab画出照度数据 }h +a8@  
8. 在Matlab计算照度平均值 nKu`Ta*fX  
9. 返回数据到FRED中 R>/M>*C
