[推荐]FRED案例-FRED如何调用Matlab [复制链接]

{KYbsD  
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。 }JyWy_Y

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： @|! 9~F  
enableservice('AutomationServer', true) STmn%&  
    enableservice('AutomationServer') iTJSW  
'~Uo+<v$w  
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。 a=}JW]

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： `oQ)qa_  
1. 在FRED脚本编辑界面找到参考. hyqsMkW|  
2. 找到Matlab Automation Server Type Library gU1E6V-Jm  
    3. 将名字改为MLAPP o%_MTCANy

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。 q y"VrR

1. 创建Matlab服务器。 D5x }V  
2. 移动探测面对于前一聚焦面的位置。 NfqJ>[}I+  
3. 在探测面追迹光线 qd\5S*Z1  
4. 在探测面计算照度 &iCE/
  
5. 使用PutWorkspaceData发送照度数据到Matlab /c

    6. 使用PutFullMatrix发送标量场数据到Matlab中 ."9t<<!  
7. 用Matlab画出照度数据
