[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。 0MwG}|RC  
=?meO0]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： z1B
j
_u{  
enableservice('AutomationServer', true) Gl?P.BCW.&  
enableservice('AutomationServer') X@6zI-Y%  
:N^@a-  
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。 ]I{qp~^#n

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： Ck ~V5  
1. 在FRED脚本编辑界面找到参考. uB5h9&57  
2. 找到Matlab Automation Server Type Library .\z|Fr  
3. 将名字改为MLAPP =$"zqa.B6  
K$MJ#Zx^  
lH#@^i|G  
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)YWFZZc

现在将脚本代码公布如下，此脚本执行如下几个步骤： <.PPs:{8#  
1. 创建Matlab服务器。 w5dIk]T  
2. 移动探测面对于前一聚焦面的位置。 09}f\/  
3. 在探测面追迹光线 l|@/?GaH  
4. 在探测面计算照度 K#9(|2J%  
5. 使用PutWorkspaceData发送照度数据到Matlab `-72>F;T  
6. 使用PutFullMatrix发送标量场数据到Matlab中 &=s|  
7. 用Matlab画出照度数据 E1Ru)k{B  
8. 在Matlab计算照度平均值 &%f]-=~  
9. 返回数据到FRED中 4b3F9
