[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。 {~Phc 2z  
(Y-
7B  
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： IuRKj8J)o  
enableservice('AutomationServer', true) W4Zi?@L>'  
enableservice('AutomationServer') ^G5_d"Gr  
;0ake%v]  
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。 ."9v1kW

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： `?~pk)<C].  
1. 在FRED脚本编辑界面找到参考. SC'fT!  
2. 找到Matlab Automation Server Type Library U*)pUJ{&t  
3. 将名字改为MLAPP !)ee{CwNc

VNF@)!l  
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。 x#'# ~EO-G

现在将脚本代码公布如下，此脚本执行如下几个步骤： sY=$\hj  
1. 创建Matlab服务器。 \ VJ3  
2. 移动探测面对于前一聚焦面的位置。 k|1/gd5  
3. 在探测面追迹光线 Ow<=K:^  
4. 在探测面计算照度 waldLb>7D  
5. 使用PutWorkspaceData发送照度数据到Matlab (J5E]NV  
6. 使用PutFullMatrix发送标量场数据到Matlab中 S$ dFz  
7. 用Matlab画出照度数据 ;ZB[g78%R%  
8. 在Matlab计算照度平均值 _r&`[@m  
9. 返回数据到FRED中 GoZr[=d
