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。 {N4 'g_  
"cKD#  
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: V~*Gk!+f  
enableservice('AutomationServer', true) |]?f6^ |4  
enableservice('AutomationServer') |OH*c3~r  
&=g3J4$z  
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。 o[ZjXLJzV

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: hIe.Mv-I)  
1. 在FRED脚本编辑界面找到参考. fDy*dp4z  
2. 找到Matlab Automation Server Type Library D S U`(`  
3. 将名字改为MLAPP 0/R;g~q@  
?Y4 +3`\x  
FRQ.ix2  
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 %`7(bN

现在将脚本代码公布如下,此脚本执行如下几个步骤: \zBi-GI7  
1. 创建Matlab服务器。  d$$5&a  
2. 移动探测面对于前一聚焦面的位置。 dn 6]qW5  
3. 在探测面追迹光线 EF)BezG5y  
4. 在探测面计算照度 w+)${|N?  
5. 使用PutWorkspaceData发送照度数据到Matlab z!g$#hmL>  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W.j^L;  
7. 用Matlab画出照度数据 }4C_r'd6  
8. 在Matlab计算照度平均值 #[ prG  
9. 返回数据到FRED中 w;O-ATUzN
