[分享]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。 XknNb{. r  
F`,bFQ  
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： I3x+pa^]2  
enableservice('AutomationServer', true)  k6@  
enableservice('AutomationServer') egfd=z=2un  
PV=sqLM~  
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。 |)O;+e\

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： .S=|ZP+  
1. 在FRED脚本编辑界面找到参考. m%"=sX

2. 找到Matlab Automation Server Type Library fffWvf  
3. 将名字改为MLAPP } MP_

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。 k!+v*+R+V

1. 创建Matlab服务器。 !>K=@9NC|.  
2. 移动探测面对于前一聚焦面的位置。 t

3. 在探测面追迹光线 mc,HliiJ  
4. 在探测面计算照度 ~e){2_J&n  
5. 使用PutWorkspaceData发送照度数据到Matlab ^y|`\oyqwN  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6B>*v`T:  
7. 用Matlab画出照度数据 Ln\Gv/)  
8. 在Matlab计算照度平均值 2AxKB+c1`  
9. 返回数据到FRED中 NW21{}=4
