[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。 hy/g*>  
~,,r\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： h<L_ =)lH  
enableservice('AutomationServer', true) ybpOk  
enableservice('AutomationServer') <pp
dy,j:  
olv&K(-ccI  
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。 e;v7!X

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： (jKqwVs.:  
1. 在FRED脚本编辑界面找到参考. Q``1^E'  
2. 找到Matlab Automation Server Type Library l#uF%;GDX  
3. 将名字改为MLAPP 0L;,\&*u  
j6s j2D  
?* ~4~ZEE  
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。 Ztk%uc8_lM

现在将脚本代码公布如下，此脚本执行如下几个步骤： Ew4D';&;  
1. 创建Matlab服务器。 ,`U>BBBLv  
2. 移动探测面对于前一聚焦面的位置。 B<~AUf*y  
3. 在探测面追迹光线 '!$QI@@  
4. 在探测面计算照度 <j,I@%  
5. 使用PutWorkspaceData发送照度数据到Matlab #

6. 使用PutFullMatrix发送标量场数据到Matlab中 A}!
A*z<9  
7. 用Matlab画出照度数据 SN|!FW.*:  
8. 在Matlab计算照度平均值 6l,6k~Z9  
9. 返回数据到FRED中 h0-.9ym
