[推荐]FRED案例-FRED如何调用Matlab [复制链接]

@Z0. }}Y  
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。 hGFi|9/-u  
U["<f`z4\  
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： mq{Z Q'  
enableservice('AutomationServer', true) d{TcjZ  
    enableservice('AutomationServer') CCpRQKb=  
'4
{@F~fu  
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。 /{({f?k<\/  
]:ca=&>  
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： `LH9@Z{  
1. 在FRED脚本编辑界面找到参考. 6l|L/Z_6  
2. 找到Matlab Automation Server Type Library QM!UMqdj  
    3. 将名字改为MLAPP A@M2(?w4

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。 ks$5$,^T2o

1. 创建Matlab服务器。 lBn<\Y!^  
2. 移动探测面对于前一聚焦面的位置。 ]Vfp,"op  
3. 在探测面追迹光线 2w8YtM3+"z  
4. 在探测面计算照度 DmoY],9I+p  
5. 使用PutWorkspaceData发送照度数据到Matlab ~m R^j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !'\(OFv9Im  
7. 用Matlab画出照度数据 7|Vpk&.>  
8. 在Matlab计算照度平均值 1`II%mf[  
9. 返回数据到FRED中 8<Nz34Y
