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。 (%}T\~`1z#  
^1s!OT Is  
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: rbiNp6AdL  
enableservice('AutomationServer', true) 1L]7*NJe  
enableservice('AutomationServer') Z.am^Q^Y!  
jJk M:iR  
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。 lTY%,s  
C)~YWx@v  
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: PVP,2Yq!  
1. 在FRED脚本编辑界面找到参考. \(Dq=UzQI  
2. 找到Matlab Automation Server Type Library gcqcY  
3. 将名字改为MLAPP 4:q<<vCJv  
QWH1xId  
 7?-eR-  
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。 f#_XR

现在将脚本代码公布如下,此脚本执行如下几个步骤: b Gq0k&  
1. 创建Matlab服务器。 7 Bm 18  
2. 移动探测面对于前一聚焦面的位置。 X&o!xV -+  
3. 在探测面追迹光线 {Z 3t0F  
4. 在探测面计算照度 _P 0,UgZz  
5. 使用PutWorkspaceData发送照度数据到Matlab fzO4S^mTo8  
6. 使用PutFullMatrix发送标量场数据到Matlab中 VgtW T`F.I  
7. 用Matlab画出照度数据 rUEoz|e4a  
8. 在Matlab计算照度平均值 xT70Rp(2po  
9. 返回数据到FRED中 m^rgzx19?
