[分享]FRED如何调用Matlab [复制链接]

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。 yXppu[=  
6rt.ec(  
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： 5
U3="L  
enableservice('AutomationServer', true)
q'3=  
enableservice('AutomationServer') 0D|^S<z6  
n|SsV  
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。 $62ospR^Y

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： S=krF yFw  
1. 在FRED脚本编辑界面找到参考. L;fhJ~r  
2. 找到Matlab Automation Server Type Library 6;I&{9  
3. 将名字改为MLAPP +To{Tm-  
kIrME:  
m,Q<4'  
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。 R7Zx

现在将脚本代码公布如下，此脚本执行如下几个步骤： @]Iku6d-  
1. 创建Matlab服务器。 {\;CGoN|  
2. 移动探测面对于前一聚焦面的位置。 V_Wv(G0-\  
3. 在探测面追迹光线 IA$:r@QNx8  
4. 在探测面计算照度 R\A5f\L9  
5. 使用PutWorkspaceData发送照度数据到Matlab wcsUb9(  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ="d}:Jl  
7. 用Matlab画出照度数据 1W$@ V!  
8. 在Matlab计算照度平均值 -zN*2T  
9. 返回数据到FRED中 IZi1N
