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。 ( *Xn"o  
X.#)CB0c1Q  
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: y?3.W  
enableservice('AutomationServer', true) 50j8+xJPV  
enableservice('AutomationServer') [ r8 ZAS  
H=Ilum06  
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。 "J`&"_CyZ  
C!a1.&HHZ7  
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: i5t6$|u:&m  
1. 在FRED脚本编辑界面找到参考. S.)Jp -&K  
2. 找到Matlab Automation Server Type Library @(~:JP?KNC  
3. 将名字改为MLAPP 80wzn,o S

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。 6:O<k2=2

现在将脚本代码公布如下,此脚本执行如下几个步骤:  7P7OTN  
1. 创建Matlab服务器。 ^w.hI5ua)  
2. 移动探测面对于前一聚焦面的位置。 -g]Rs!w'  
3. 在探测面追迹光线 <ZF|2  
4. 在探测面计算照度 ^Aq0<  
5. 使用PutWorkspaceData发送照度数据到Matlab 8s@N NjV  
6. 使用PutFullMatrix发送标量场数据到Matlab中 sfj+-se(K.  
7. 用Matlab画出照度数据 odsFgh  
8. 在Matlab计算照度平均值 sa(.Anmlj  
9. 返回数据到FRED中 "(^XZAU#W
