[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。 RE/'E?G  
,aS6|~ac4  
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： VD+TJ` r  
enableservice('AutomationServer', true) 8v)pPJr  
enableservice('AutomationServer') K FV&Dt}<  
^sIxR*C[v  
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。 O-- "\4  
W 0^.Dx  
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： n[4F\I>  
1. 在FRED脚本编辑界面找到参考. -;=0dfC(  
2. 找到Matlab Automation Server Type Library @dE|UZ=(  
3. 将名字改为MLAPP "3CQ0  
kQ4-W9u  
f?: o  
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。 -1t"(v

现在将脚本代码公布如下，此脚本执行如下几个步骤： ;taTdzR_  
1. 创建Matlab服务器。 '6i"pJ0%  
2. 移动探测面对于前一聚焦面的位置。 Arh0m. w  
3. 在探测面追迹光线 [ L% -lJ  
4. 在探测面计算照度 PY=(|2tb4  
5. 使用PutWorkspaceData发送照度数据到Matlab TJ9JIxnS  
6. 使用PutFullMatrix发送标量场数据到Matlab中 D?~`L[}I!}  
7. 用Matlab画出照度数据 BeZr5I"`}  
8. 在Matlab计算照度平均值 i-Ck:-J  
9. 返回数据到FRED中 '&@'V5}C{
