[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。 (#dwIBBFt  
cWd\Ki  
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： MQ9Nn|4  
enableservice('AutomationServer', true) 9rB,7%@EL  
enableservice('AutomationServer') +x7b9sHJ  
Z#+{ksU  
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。 S690Y]:h$v

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： aaN|g{pX  
1. 在FRED脚本编辑界面找到参考. /``4!jU  
2. 找到Matlab Automation Server Type Library ^x! N]  
3. 将名字改为MLAPP 4oY<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。 !N`$`qAK

1. 创建Matlab服务器。 H%!ED1zpA  
2. 移动探测面对于前一聚焦面的位置。 O#}'QZd'  
3. 在探测面追迹光线 %s+H& vfQs  
4. 在探测面计算照度 igoXMsifT+  
5. 使用PutWorkspaceData发送照度数据到Matlab Ya#,\;dTT  
6. 使用PutFullMatrix发送标量场数据到Matlab中 MH"{N "|  
7. 用Matlab画出照度数据 ?r~|B/]  
8. 在Matlab计算照度平均值 {^r8uKo:~  
9. 返回数据到FRED中 8{m5P8w'
