[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。 \T4v|Pw\  
%^?fMeI|Y  
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： 5dx$HE&b)  
enableservice('AutomationServer', true) I:=S0&%)  
enableservice('AutomationServer') M1k{t%M+S  
!{ y@od@T  
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。 4GkWRu1

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： )1]ZtU  
1. 在FRED脚本编辑界面找到参考. 3U<cWl@  
2. 找到Matlab Automation Server Type Library VpE*(i$  
3. 将名字改为MLAPP JgxtlYjl

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。 @3>u@

现在将脚本代码公布如下，此脚本执行如下几个步骤： g{7.r-uu  
1. 创建Matlab服务器。 5VfyU8)7X  
2. 移动探测面对于前一聚焦面的位置。 ayn)5q/z  
3. 在探测面追迹光线 .e

4. 在探测面计算照度 i[O& )N,c  
5. 使用PutWorkspaceData发送照度数据到Matlab ncZ+gzK|"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~Q Oe##  
7. 用Matlab画出照度数据 |-fgj'  
8. 在Matlab计算照度平均值 +>8'mf  
9. 返回数据到FRED中 =J18eH!]
