[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。 y5@#leM  
xE>jlr?  
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： M[eq)a$  
enableservice('AutomationServer', true) l<3X:)  
enableservice('AutomationServer') WZ@hP'Zc  
;*{"|l qe  
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。 nm#ISueh

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： ]u5B]ZQnA  
1. 在FRED脚本编辑界面找到参考.

2. 找到Matlab Automation Server Type Library Ow"e3]}Mt  
3. 将名字改为MLAPP ZYS`M?Au

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。 8n&Gn%DvX

现在将脚本代码公布如下，此脚本执行如下几个步骤： }yzCq+
  
1. 创建Matlab服务器。 ]3D>ai?  
2. 移动探测面对于前一聚焦面的位置。 N4HIQ\p  
3. 在探测面追迹光线 Wg5<@=x!G  
4. 在探测面计算照度 ']bw37_U,  
5. 使用PutWorkspaceData发送照度数据到Matlab 0#G@F5; <  
6. 使用PutFullMatrix发送标量场数据到Matlab中 @1w[~QlV  
7. 用Matlab画出照度数据 A4~-{.w=  
8. 在Matlab计算照度平均值 ?<
