[技术]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。 Tc
KvSdr'  
^/DII`A  
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： n,?IcDU~m  
enableservice('AutomationServer', true) ^?s~Fk_V  
enableservice('AutomationServer') P"bknXL  
gVnw
sE  
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。 W`Q$t56

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： W%>i$:Qq  
1. 在FRED脚本编辑界面找到参考. t8DL9RW'  
2. 找到Matlab Automation Server Type Library {C/L5cZ]J  
3. 将名字改为MLAPP xMNNXPz(  
+dCDM1{_a

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。 S$jV|xKB

现在将脚本代码公布如下，此脚本执行如下几个步骤： Np|'7D  
1. 创建Matlab服务器。 g5tjj.  
2. 移动探测面对于前一聚焦面的位置。 Sa;<B:|  
3. 在探测面追迹光线 ([,vX"4  
4. 在探测面计算照度 'dIX=/RZ  
5. 使用PutWorkspaceData发送照度数据到Matlab 8_a$kJJ2  
6. 使用PutFullMatrix发送标量场数据到Matlab中 *L%6qxl`V  
7. 用Matlab画出照度数据 j3x^<a\gJ  
8. 在Matlab计算照度平均值 HzRX$IKB3(  
9. 返回数据到FRED中 bJQ5- *F
