[推荐]FRED案例-FRED如何调用Matlab [复制链接]

$sILCn  
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。 <@.

g9~QNA  
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： P>U7RX e  
enableservice('AutomationServer', true) $I0&I[_LzK  
    enableservice('AutomationServer') '@6O3z_{  
.n\j<Kq  
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。 1S{AGgls5

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： O'rz  
1. 在FRED脚本编辑界面找到参考. O[Y

2. 找到Matlab Automation Server Type Library k,,Bf-?  
    3. 将名字改为MLAPP N({0"7

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。 F:~k4uTW\b

2. 移动探测面对于前一聚焦面的位置。 0<[g7BbR  
3. 在探测面追迹光线 Um~DA  
4. 在探测面计算照度 Ir6(EIwx0  
5. 使用PutWorkspaceData发送照度数据到Matlab Je*hyi7
