[技术]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。 Iq0[Kd0.

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： 9xN`  
enableservice('AutomationServer', true) 6`h}#@ (  
enableservice('AutomationServer') l\/uXP?  
\wKnX]xGf  
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。 B:>>D/O

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. 在FRED脚本编辑界面找到参考. O:]e4r,'  
2. 找到Matlab Automation Server Type Library S`Xx('!/|  
3. 将名字改为MLAPP b$

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。 c(kYCVc

现在将脚本代码公布如下，此脚本执行如下几个步骤： cCx_tGR"  
1. 创建Matlab服务器。 *`_2uBz  
2. 移动探测面对于前一聚焦面的位置。 S l

3. 在探测面追迹光线 :caXQ)
  
4. 在探测面计算照度 k|^YYi=xF  
5. 使用PutWorkspaceData发送照度数据到Matlab O@>ZYA%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [w*]\x'S  
7. 用Matlab画出照度数据 ~c=F$M^"c  
8. 在Matlab计算照度平均值 v@d]*TG  
9. 返回数据到FRED中 35H.ZXQp-
