[推荐]FRED案例-FRED如何调用Matlab [复制链接]

7z5AI!s_  
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。

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： xBl}=M?Qu  
enableservice('AutomationServer', true) B ,e3r  
    enableservice('AutomationServer') mst-:F[h  

$:{uF#  
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。 OqHD=D[  
?.,..p  
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： /2~qm/%Q  
1. 在FRED脚本编辑界面找到参考. bt-y6,> +E  
2. 找到Matlab Automation Server Type Library vqJiMa j@Z  
    3. 将名字改为MLAPP 5ju\!Re3X  
     g()YP

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。 b:+.Y$%F-

2. 移动探测面对于前一聚焦面的位置。 &3:-(:<U  
3. 在探测面追迹光线 "2o)1G  
4. 在探测面计算照度 wS hsu_(i  
5. 使用PutWorkspaceData发送照度数据到Matlab |36d<b Io  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l]uF!']f  
7. 用Matlab画出照度数据 gcQ>:mi  
8. 在Matlab计算照度平均值 K*d+
