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。 4,8=0[eRG  
.Ulrv5wJ  
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: MeXzWLH  
enableservice('AutomationServer', true) He#5d!cf:M  
enableservice('AutomationServer') V &K:~[M  
 p)5j~Nl  
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。 <5 R`E(

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: (]JZ1s|  
1. 在FRED脚本编辑界面找到参考. Y#>'.$ (Az  
2. 找到Matlab Automation Server Type Library .?L&k|wX-  
3. 将名字改为MLAPP Uxla,CCp-

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。 8 JOfx

现在将脚本代码公布如下,此脚本执行如下几个步骤: F/MzrK\':m  
1. 创建Matlab服务器。 6}Se$XMl  
2. 移动探测面对于前一聚焦面的位置。 -dCM eC  
3. 在探测面追迹光线 Q&zEa0^rG6  
4. 在探测面计算照度 DB1GW,  
5. 使用PutWorkspaceData发送照度数据到Matlab ^hG Y,\K9  
6. 使用PutFullMatrix发送标量场数据到Matlab中 L/2{}l>D  
7. 用Matlab画出照度数据 IO,ddVO  
8. 在Matlab计算照度平均值 {s=n "*Qp)  
9. 返回数据到FRED中 ,QDS_u$xi&
