[推荐]FRED案例-FRED如何调用Matlab [复制链接]

7F0J*M  
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。 *(1<J2j  
?xH{7)dO  
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： M>m!\bb%.  
enableservice('AutomationServer', true) 2"Wq
=qy\J  
    enableservice('AutomationServer') n@ba>m4{  
vJGH8$%;,  
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。 9%|skTgIqH

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： 48^C+#Jbc  
1. 在FRED脚本编辑界面找到参考. 4GF3.?3  
2. 找到Matlab Automation Server Type Library %n9ukc~$p  
    3. 将名字改为MLAPP rZpsC}C'

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。 =,;$d&#*h

1. 创建Matlab服务器。 X41Qkf

2. 移动探测面对于前一聚焦面的位置。 0(Y,Q(JTo&  
3. 在探测面追迹光线 4[x`\  
4. 在探测面计算照度 AQ(n?1LU  
5. 使用PutWorkspaceData发送照度数据到Matlab )@I] Rk?  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ysK J=  
7. 用Matlab画出照度数据 Ewr2popK  
8. 在Matlab计算照度平均值 2e1%L,y{W  
9. 返回数据到FRED中 TO5y.M|7
