[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。 J-f0  
V$_0VN'+Z  
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： s*X\%!l9  
enableservice('AutomationServer', true) [O)Zof  
enableservice('AutomationServer') 2Ee1mbZVw8  
k:qou})#4  
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。 ).S<{zm7  
w+Z};C  
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： UKBMGzu2:  
1. 在FRED脚本编辑界面找到参考. WuQYEbap  
2. 找到Matlab Automation Server Type Library lG+ltCc$9  
3. 将名字改为MLAPP 5q#|sVT7R  
3d<HIG^W}  
;E"mB4/)  
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。 iHn]yv3 #

现在将脚本代码公布如下，此脚本执行如下几个步骤： Cr%r<*s  
1. 创建Matlab服务器。 U:|v(U$"?  
2. 移动探测面对于前一聚焦面的位置。 F)5Aq H/p
 
3. 在探测面追迹光线 *Kkw,qp/  
4. 在探测面计算照度 O*v+<|0!l  
5. 使用PutWorkspaceData发送照度数据到Matlab pd

6. 使用PutFullMatrix发送标量场数据到Matlab中 bx^EaXj(r  
7. 用Matlab画出照度数据 T!A}ipqb  
8. 在Matlab计算照度平均值 B3t>M) 9  
9. 返回数据到FRED中 ?t42=nvf
