[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。 ;$1x_ Cb  
X2;72  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： "VHT5k  
enableservice('AutomationServer', true) k h*WpX  
enableservice('AutomationServer') 1Z;cb0:  
Vr"'O
6  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 a5O$he

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： #`=>Mza  
1. 在FRED脚本编辑界面找到参考. M #0v# {o  
2. 找到Matlab Automation Server Type Library . XbDb  
3. 将名字改为MLAPP n[qnrk*3 %

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。 OC-d5P

现在将脚本代码公布如下，此脚本执行如下几个步骤： I![/bwObG  
1. 创建Matlab服务器。 ^jd

2. 移动探测面对于前一聚焦面的位置。 sa/9r9hc+  
3. 在探测面追迹光线 vN@0

4. 在探测面计算照度 Pg`+Q^^6S  
5. 使用PutWorkspaceData发送照度数据到Matlab

6. 使用PutFullMatrix发送标量场数据到Matlab中 ubsv\[:C  
7. 用Matlab画出照度数据 UHTxNK@}  
8. 在Matlab计算照度平均值 kB5y}v.3 S  
9. 返回数据到FRED中 z#|Auc0
