[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。 t"Ci1"U  
C+uW]]~I)  
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： nX 9]dz
 
enableservice('AutomationServer', true) ]VxC]a2  
enableservice('AutomationServer') _crhBp5@T3  
SF&2a(~s  
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。 g\fj6

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： 5LB{b]w7m  
1. 在FRED脚本编辑界面找到参考. }mXYS|{  
2. 找到Matlab Automation Server Type Library ?!&%-R6*  
3. 将名字改为MLAPP t+}

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。 ,bXZ<RY$

现在将脚本代码公布如下，此脚本执行如下几个步骤： e~'lWJD  
1. 创建Matlab服务器。 iW^J>aKy
 
2. 移动探测面对于前一聚焦面的位置。 T"[]'|'  
3. 在探测面追迹光线 5\MC5us3  
4. 在探测面计算照度 UPU$SZAIx  
5. 使用PutWorkspaceData发送照度数据到Matlab z,G_&5|f%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 kFwFPK%B  
7. 用Matlab画出照度数据 ey=KA

8. 在Matlab计算照度平均值 H:]cBk^[,  
9. 返回数据到FRED中 P2a5<#_|
