[推荐]FRED案例-FRED如何调用Matlab [复制链接]

:v''"+\  
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。 d+1L5}Jn  
upZYv~Sa  
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： B44]NsYks~  
enableservice('AutomationServer', true) \qRjXadj  
    enableservice('AutomationServer') 'aLPTVM^  
38OIFT  
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。 *

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： /0X0#+kn  
1. 在FRED脚本编辑界面找到参考. }u38:(^`ai  
2. 找到Matlab Automation Server Type Library ]i9H_K  
    3. 将名字改为MLAPP #wq

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。 FA<Z37:

现在将脚本代码公布如下，此脚本执行如下几个步骤：  m,xy4  
1. 创建Matlab服务器。 j&o/X7I=  
2. 移动探测面对于前一聚焦面的位置。 D>,$c  
3. 在探测面追迹光线 eYnLZ&H5O  
4. 在探测面计算照度 8HHgN`_  
5. 使用PutWorkspaceData发送照度数据到Matlab =k[(rvU3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Hz8Jgp  
7. 用Matlab画出照度数据 xP<H,og&x=  
8. 在Matlab计算照度平均值 ./aZ

9. 返回数据到FRED中 hqwz~Ky}
