[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。 Z:7X=t=  
VbQ9o  
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： t 1gH9  
enableservice('AutomationServer', true) [+dOgyK  
enableservice('AutomationServer') ozv:$>v@"  
f7NK0kuA  
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。 Q%:#xG5AmE

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： lt%bGjk  
1. 在FRED脚本编辑界面找到参考. l;_zXN  
2. 找到Matlab Automation Server Type Library fS2 ^$"B|  
3. 将名字改为MLAPP OY$P8y3MY

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。 ,I# X[^/

现在将脚本代码公布如下，此脚本执行如下几个步骤： rWk4)+Tk  
1. 创建Matlab服务器。 O :P%gz4  
2. 移动探测面对于前一聚焦面的位置。 mNUc g{+/  
3. 在探测面追迹光线 K& / rzs-  
4. 在探测面计算照度 Ip_S8 ;;  
5. 使用PutWorkspaceData发送照度数据到Matlab B]jI^(P  
6. 使用PutFullMatrix发送标量场数据到Matlab中 3e~X`K1Q<  
7. 用Matlab画出照度数据
k\,01

8. 在Matlab计算照度平均值 V$e\84<  
9. 返回数据到FRED中 'Y`.0T[&
