[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。 l85O-g}M  
(di
)`D5Q  
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： =H L9Z  
enableservice('AutomationServer', true) ]w5ji  
enableservice('AutomationServer') [))gn  
p, !
1 3X  
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。 t- !h X/

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： 3`mC"ab /  
1. 在FRED脚本编辑界面找到参考. S6=\r{V  
2. 找到Matlab Automation Server Type Library @2QJm
 
3. 将名字改为MLAPP M|$H+e }:

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。  ]v/t8`

现在将脚本代码公布如下，此脚本执行如下几个步骤： @WMj^t1D+  
1. 创建Matlab服务器。 cYBrRTrI#  
2. 移动探测面对于前一聚焦面的位置。 lqhHb

3. 在探测面追迹光线 O8!!UA8V  
4. 在探测面计算照度 TG""eC!E  
5. 使用PutWorkspaceData发送照度数据到Matlab l6r%nHP@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 pT|./ Fe  
7. 用Matlab画出照度数据 =MQ2sb  
8. 在Matlab计算照度平均值 E&}H\zt#  
9. 返回数据到FRED中 !NlB%
