[技术]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。 ;7bY>zc(w  
zJT,Hv .  
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： k{ibD5B  
enableservice('AutomationServer', true) Z$
2Vd`XP  
enableservice('AutomationServer') ^5~)m6=2  
kYU!6t1  
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。 ZA8FX

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： m_,j)A%  
1. 在FRED脚本编辑界面找到参考. p^i]{"sjbU  
2. 找到Matlab Automation Server Type Library O`FuXB(t  
3. 将名字改为MLAPP i=j4Wg,{J

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。 =*Y=u6?

现在将脚本代码公布如下，此脚本执行如下几个步骤： KSy.  
1. 创建Matlab服务器。 i*ji   
2. 移动探测面对于前一聚焦面的位置。 8`;3`lZ  
3. 在探测面追迹光线 A3mSSc6  
4. 在探测面计算照度 ~.

5. 使用PutWorkspaceData发送照度数据到Matlab H\ONv=}7I  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?8aPd"x  
7. 用Matlab画出照度数据 }*3#*y "  
8. 在Matlab计算照度平均值 ~ZXAW~a}  
9. 返回数据到FRED中 iMXK_O%
