[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。 E M
Kv)5MH  
N)Z,/w9  
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： hGvuA9d~  
enableservice('AutomationServer', true) KC{HX?  
enableservice('AutomationServer') /\M3O  
9y"*H2$#  
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。 Rm!Iv&{

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： u=h/l!lR  
1. 在FRED脚本编辑界面找到参考. !j?2HlIK+  
2. 找到Matlab Automation Server Type Library QR($KW(  
3. 将名字改为MLAPP HGpj(U:`c

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。 L?e N(L

1. 创建Matlab服务器。 dRXF5Ox5K}  
2. 移动探测面对于前一聚焦面的位置。 3Vl?;~ :5  
3. 在探测面追迹光线 SXA_P{j&a  
4. 在探测面计算照度 2!b+}+:  
5. 使用PutWorkspaceData发送照度数据到Matlab Q}M% \v  
6. 使用PutFullMatrix发送标量场数据到Matlab中 D f H>UA  
7. 用Matlab画出照度数据 +,"/z\QO  
8. 在Matlab计算照度平均值 .* xaI+:  
9. 返回数据到FRED中 EnGVp<6R
