[推荐]FRED案例-FRED如何调用Matlab [复制链接]

1 C[#]krh  
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。 ~r>WnI:vg  
UbMcXH8=F  
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： '*)!&4f  
enableservice('AutomationServer', true) b<:s{f"t,  
    enableservice('AutomationServer') ;>Z#1~8  
hXMC!~Th  
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。 [3/P EDkw

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： %*jpQOw  
1. 在FRED脚本编辑界面找到参考. ef53~x  
2. 找到Matlab Automation Server Type Library KP:O]520  
    3. 将名字改为MLAPP CTPn'P=\C  
     n,AN&BZ  
     sPd5f2'  
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。 6j` waK

1. 创建Matlab服务器。 [r]USCq  
2. 移动探测面对于前一聚焦面的位置。 d628@~Ekn  
3. 在探测面追迹光线 R[_7ab]A  
4. 在探测面计算照度 oh:t ex<  
5. 使用PutWorkspaceData发送照度数据到Matlab Nwu#,f=X  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +vYm:  
7. 用Matlab画出照度数据 m{V

8. 在Matlab计算照度平均值 )<3WVvB  
9. 返回数据到FRED中 # ^%'*/z
