[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。 Uij$ eBN  
&6EfybAt^_  
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： *?'T8yf^  
enableservice('AutomationServer', true) S>Y?QQ3#wp  
enableservice('AutomationServer') ?g.w%Mf*  
_ji%BwJ  
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。 wH<*

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： _Pal)re]U  
1. 在FRED脚本编辑界面找到参考.
`lzH:B  
2. 找到Matlab Automation Server Type Library vt,X:3  
3. 将名字改为MLAPP hn.fX:}

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。 _,Y79 b6

1. 创建Matlab服务器。 X}Fv*  
2. 移动探测面对于前一聚焦面的位置。 L|?tcic  
3. 在探测面追迹光线 g!uhy}  
4. 在探测面计算照度 ]CYe=m1<2Q  
5. 使用PutWorkspaceData发送照度数据到Matlab bE"CSK#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8%Lg)hvl  
7. 用Matlab画出照度数据 <^paRKEa+#
