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。 60D36b(  
ys_2?uv  
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: 6Q.S  
enableservice('AutomationServer', true) 1{}p_"s>  
enableservice('AutomationServer') 0;Z|:\P\=  
a#oROb-*~  
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。 .;#T<S "

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: +pofN-*%  
1. 在FRED脚本编辑界面找到参考. *~rj!N?;  
2. 找到Matlab Automation Server Type Library }Zhe%M=}G  
3. 将名字改为MLAPP TlG>)Z@/

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。 B2`S0 H

现在将脚本代码公布如下,此脚本执行如下几个步骤: 6].[z+  
1. 创建Matlab服务器。 }nmlN  
2. 移动探测面对于前一聚焦面的位置。 'Zx5+rM${}  
3. 在探测面追迹光线 j"W>fC/u  
4. 在探测面计算照度 `e[S Zj\  
5. 使用PutWorkspaceData发送照度数据到Matlab c*USA eP  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Gnc`CyN:H  
7. 用Matlab画出照度数据 2e48L677-  
8. 在Matlab计算照度平均值 EF/d7  
9. 返回数据到FRED中 0<M-asI?
