[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。 |LwW/

(X(296<;  
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： TlA*~HG
<Q  
enableservice('AutomationServer', true) .bT+#x  
enableservice('AutomationServer') t]QGyW A]  
{ yvKUTq`  
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。 ,]\:]Y&?

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： M.loG4r!
 
1. 在FRED脚本编辑界面找到参考. |*5QFp  
2. 找到Matlab Automation Server Type Library -eA3o2'  
3. 将名字改为MLAPP aglW\LT^

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。 Bp.z6x4

1. 创建Matlab服务器。

2. 移动探测面对于前一聚焦面的位置。 R[/]iK+!&  
3. 在探测面追迹光线 :q+D`s  
4. 在探测面计算照度 LM~,`#3Ru  
5. 使用PutWorkspaceData发送照度数据到Matlab VHUOI64*  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ,fQs+*j  
7. 用Matlab画出照度数据 CK{.Ic^  
8. 在Matlab计算照度平均值 @NY$.K#]  
9. 返回数据到FRED中 +"!=E erKi
