[推荐]FRED案例-FRED如何调用Matlab [复制链接]

.Px,=56$X  
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。 ri;r7Y9V9`  
QD6Z=>?S  
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： ~M(pCSJ[  
enableservice('AutomationServer', true) |O^V)bZmx  
    enableservice('AutomationServer') P:vX }V |[  
-hm9sNox  
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。  2fbvU

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： 4>d[qr*<  
1. 在FRED脚本编辑界面找到参考. Xek E#

2. 找到Matlab Automation Server Type Library DwQp$l'NfW  
    3. 将名字改为MLAPP <`b|

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。 (rMTW+,

1. 创建Matlab服务器。 rUhWZta  
2. 移动探测面对于前一聚焦面的位置。 ],WwqD=  
3. 在探测面追迹光线 ZO]E@?Oav  
4. 在探测面计算照度 :  ,|=Q}  
5. 使用PutWorkspaceData发送照度数据到Matlab _LLW{^V  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J#_\+G i  
7. 用Matlab画出照度数据 !G@V<'F  
8. 在Matlab计算照度平均值 LH1BZ(5g  
9. 返回数据到FRED中 3" 8t)s
