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。 L7_Mg{  
P1 =bbMk  
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: xeo;4c#S5  
enableservice('AutomationServer', true) l@4hBq  
enableservice('AutomationServer') %~J90a  
f!e8xDfA  
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。 ww nc

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: W!.UMmw`  
1. 在FRED脚本编辑界面找到参考. AvRZf-Geg  
2. 找到Matlab Automation Server Type Library cQzd0X  
3. 将名字改为MLAPP 5|x&Z/hL

u9"b,].b  
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。 U# Y ?'3:

现在将脚本代码公布如下,此脚本执行如下几个步骤: p*_g0_^  
1. 创建Matlab服务器。 )9##mUt'}  
2. 移动探测面对于前一聚焦面的位置。 c~ l$_A  
3. 在探测面追迹光线 IpGq_TU  
4. 在探测面计算照度  S&]+r<  
5. 使用PutWorkspaceData发送照度数据到Matlab I?J$";A  
6. 使用PutFullMatrix发送标量场数据到Matlab中 %bZ3^ ub}t  
7. 用Matlab画出照度数据 _D1bR7  
8. 在Matlab计算照度平均值 .Di+G-#aEs  
9. 返回数据到FRED中 knh^q;q*
