[分享]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。 L})fYVX  
(j:[<U
  
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： k^JgCC+  
enableservice('AutomationServer', true) P5dD&  
enableservice('AutomationServer')
ku57<kb  
s,C>l_4-  
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。 [$$R>ELYQ

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： 6V9r[,n  
1. 在FRED脚本编辑界面找到参考. FME,W&_d  
2. 找到Matlab Automation Server Type Library {?w*n_T.  
3. 将名字改为MLAPP |]:6IuslJ

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。 K\RMX?YsP

现在将脚本代码公布如下，此脚本执行如下几个步骤： dqU)(T=C  
1. 创建Matlab服务器。 U/HF6=Wot  
2. 移动探测面对于前一聚焦面的位置。 B}y#AVSA  
3. 在探测面追迹光线 ]9<H[5>$R  
4. 在探测面计算照度 m-[xrVV  
5. 使用PutWorkspaceData发送照度数据到Matlab tT A  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ^eV K.  
7. 用Matlab画出照度数据 5^
