[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。 pY
o=oI  
S`m,S4-eD  
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： #f{lC0~vA  
enableservice('AutomationServer', true) 2.-o@im0  
enableservice('AutomationServer') "3fBY\>
a  
M0L&~p_F  
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。 ;+U<bqL6

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： nPFwPk8=M  
1. 在FRED脚本编辑界面找到参考. khx.y
Rx  
2. 找到Matlab Automation Server Type Library JoZ(_Jh%m  
3. 将名字改为MLAPP Qz,|mo+

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。 !_~UvxM+

现在将脚本代码公布如下，此脚本执行如下几个步骤： @gY\;[#.  
1. 创建Matlab服务器。 8(f

2. 移动探测面对于前一聚焦面的位置。 kWhr1wR1  
3. 在探测面追迹光线 O_;Dk W  
4. 在探测面计算照度 ]~0}=,H$N  
5. 使用PutWorkspaceData发送照度数据到Matlab XNehPZYS  
6. 使用PutFullMatrix发送标量场数据到Matlab中 w1`QIv  
7. 用Matlab画出照度数据 g/~XCC^F?  
8. 在Matlab计算照度平均值 ,Na^%A@TJ  
9. 返回数据到FRED中 8wK ~ i
