[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。 +95: O 8  
8d|/^U.w~V  
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： +\s32o zg  
enableservice('AutomationServer', true) 7-#R[8S  
enableservice('AutomationServer') pry
po.RI  
MBp,!_Q6  
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。 dZ6\2ok+

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： oItEGJ|  
1. 在FRED脚本编辑界面找到参考. Nqy)jfyex  
2. 找到Matlab Automation Server Type Library "}|&eBH^<

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。 5~ip N/)E

现在将脚本代码公布如下，此脚本执行如下几个步骤： ^ "D  
1. 创建Matlab服务器。 g$?kL  
2. 移动探测面对于前一聚焦面的位置。 QV%,s!_b  
3. 在探测面追迹光线 {zNFp#z  
4. 在探测面计算照度 aG*Mj;J  
5. 使用PutWorkspaceData发送照度数据到Matlab e&k=fV  
6. 使用PutFullMatrix发送标量场数据到Matlab中 rl__3q  
7. 用Matlab画出照度数据 :Vnus @#r  
8. 在Matlab计算照度平均值 P#j>
