[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。 py%_XL=w,

e9lk$  
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： ~&%&Z  
enableservice('AutomationServer', true) +2 x|j>  
enableservice('AutomationServer') /DE`>eJY  
;0JK>c ]#  
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。 %^LwLyoVM  
AD@-H0Y  
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： ^b&U0k$R  
1. 在FRED脚本编辑界面找到参考. >!BZ>G2  
2. 找到Matlab Automation Server Type Library bKac?y~S_  
3. 将名字改为MLAPP SUaXm#9  
yr[HuwU  
+<$b6^>!$  
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。 `Qxdb1>mjY

现在将脚本代码公布如下，此脚本执行如下几个步骤： u8N"i
),  
1. 创建Matlab服务器。 P0O=veCf  
2. 移动探测面对于前一聚焦面的位置。 8=DZ;]XD.  
3. 在探测面追迹光线 b3^d!#KVM  
4. 在探测面计算照度 ~0T,_N  
5. 使用PutWorkspaceData发送照度数据到Matlab lCxPR'C|  
6. 使用PutFullMatrix发送标量场数据到Matlab中 2E_d$nsJ  
7. 用Matlab画出照度数据 <-s5 ;xwtS  
8. 在Matlab计算照度平均值 g'<ekY+V:  
9. 返回数据到FRED中 jImw_Q
