[技术]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。 W^Yxny  
.`lCWeHN  
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： J,hCvm  
enableservice('AutomationServer', true) ' QG?nu  
enableservice('AutomationServer') u, ff>/1  
_$'ashF  
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。 Z;i:](

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： :/#rZPPF  
1. 在FRED脚本编辑界面找到参考. 45e~6",  
2. 找到Matlab Automation Server Type Library e(sk[guvX  
3. 将名字改为MLAPP T%Lx%Qn

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。 .H|-_~Yx|

1. 创建Matlab服务器。 rsQtMtS2  
2. 移动探测面对于前一聚焦面的位置。 g(052]  
3. 在探测面追迹光线 S!UaH>Rh  
4. 在探测面计算照度 n]9$:aLZ  
5. 使用PutWorkspaceData发送照度数据到Matlab /(cPfZZ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 pkzaNY/q  
7. 用Matlab画出照度数据 zdYjF|  
8. 在Matlab计算照度平均值 :]KAkhFkbb  
9. 返回数据到FRED中 |N2#I
