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。 PZH]9[H  
<W\~A$  
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: k(hes3JV  
enableservice('AutomationServer', true) Z.VVY\  
enableservice('AutomationServer') \+S~N:@><k  
lusINILc  
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。 Z/56JYt!~  
/koNcpJ  
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: #p*OLQ3~  
1. 在FRED脚本编辑界面找到参考. y]M/oH  
2. 找到Matlab Automation Server Type Library N.BD]_C  
3. 将名字改为MLAPP a<c %Xy/  
vZ$uD,@;.

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。 PX(Gx%s|

现在将脚本代码公布如下,此脚本执行如下几个步骤: Q)HVh[4  
1. 创建Matlab服务器。 n5oB#>tI0  
2. 移动探测面对于前一聚焦面的位置。 ){R_o5  
3. 在探测面追迹光线 .U9NQwd  
4. 在探测面计算照度 [-1Nn}  
5. 使用PutWorkspaceData发送照度数据到Matlab :uhvDYp(-  
6. 使用PutFullMatrix发送标量场数据到Matlab中 luLm:NWUM  
7. 用Matlab画出照度数据 wxr93$v  
8. 在Matlab计算照度平均值 fd*=`+P  
9. 返回数据到FRED中 ZK3?"|vhC
