[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。 ,GhS[VJjR  
kYP#SH/  
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： e{'BAj  
enableservice('AutomationServer', true) [B*x-R[FI  
enableservice('AutomationServer') R6<X%*&%  
Z!a=dnwHz  
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。 7dTkp!'X-

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： 6m/r+?'  
1. 在FRED脚本编辑界面找到参考. +/4A  
2. 找到Matlab Automation Server Type Library ONB{_X?  
3. 将名字改为MLAPP u OmtyX

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。 z3{G9Np

1. 创建Matlab服务器。 7JD' )
 
2. 移动探测面对于前一聚焦面的位置。 WH#1zv  
3. 在探测面追迹光线 8?B!2  
4. 在探测面计算照度 ihhDOmUto  
5. 使用PutWorkspaceData发送照度数据到Matlab Hp|kQJ[LE  
6. 使用PutFullMatrix发送标量场数据到Matlab中 g>E LGG|Q  
7. 用Matlab画出照度数据 ^ glri$m  
8. 在Matlab计算照度平均值 5 Aw"B  
9. 返回数据到FRED中 <6%?OJhp
