[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。 _i3?;Fds  
DpRGPs  
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： g~7x+cu0  
enableservice('AutomationServer', true) COc,  
enableservice('AutomationServer') OO?;??  
 Wg!<V6}  
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。 Sg&0a$

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： w"Q/ 6#!K  
1. 在FRED脚本编辑界面找到参考. w@![rH6~F  
2. 找到Matlab Automation Server Type Library &@v&5EXOw  
3. 将名字改为MLAPP T'ko

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。 >Ut4INV

1. 创建Matlab服务器。 3(oB[9]s  
2. 移动探测面对于前一聚焦面的位置。 |j2$G~B6  
3. 在探测面追迹光线 Y9}ga4  
4. 在探测面计算照度 kEYkd@{  
5. 使用PutWorkspaceData发送照度数据到Matlab DqJzsk'd3  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W" i3:r  
7. 用Matlab画出照度数据 <"hq}B  
8. 在Matlab计算照度平均值 ,I2x&Ys&.  
9. 返回数据到FRED中 yC:C
