[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。 oTvg%bX  
r2f%E:-0G  
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： " :e <a?  
enableservice('AutomationServer', true) yE N3/-S+  
enableservice('AutomationServer') Pjq9BK9p  
@B0fRG y  
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。 5q4wREh

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： LntRLB'  
1. 在FRED脚本编辑界面找到参考. Ox ,Rk  
2. 找到Matlab Automation Server Type Library R[j'<gd.  
3. 将名字改为MLAPP [|$C2Dhw=

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。 [6K[P3UZx

现在将脚本代码公布如下，此脚本执行如下几个步骤： !*DYdqQ/  
1. 创建Matlab服务器。 w:I!{iX
  
2. 移动探测面对于前一聚焦面的位置。 xTG5VBv  
3. 在探测面追迹光线 YO.ddy*59  
4. 在探测面计算照度 ,V!Wo4M  
5. 使用PutWorkspaceData发送照度数据到Matlab *B4OvHi)'  
6. 使用PutFullMatrix发送标量场数据到Matlab中 cC9Zc#aK  
7. 用Matlab画出照度数据 ;|\j][A  
8. 在Matlab计算照度平均值 hH$9GL{H  
9. 返回数据到FRED中 vx$DKQK@l\
