[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。 Vlf=gP  
Qt~QJJN?oF  
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： GV"X) tGo  
enableservice('AutomationServer', true) te*|>NRS  
enableservice('AutomationServer') +
lNAog  
!l7D1i~  
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。 d%(4s~y  
P.t0o~hoK;  
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： vNn$dc  
1. 在FRED脚本编辑界面找到参考.
k@Q>(`  
2. 找到Matlab Automation Server Type Library C4h4W3w  
3. 将名字改为MLAPP M&h`uO/[  
9^zA(  
O={ ?c1i:  
在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 M~O$,dof

现在将脚本代码公布如下，此脚本执行如下几个步骤： ~]l T>|X  
1. 创建Matlab服务器。 D&]dlY@*  
2. 移动探测面对于前一聚焦面的位置。 }~bx==SF6!  
3. 在探测面追迹光线 RHj<t");  
4. 在探测面计算照度 RLE6=#4  
5. 使用PutWorkspaceData发送照度数据到Matlab OGGuVY  
6. 使用PutFullMatrix发送标量场数据到Matlab中 CW . O"_  
7. 用Matlab画出照度数据 hAvX{]  
8. 在Matlab计算照度平均值 k0>]7t$L  
9. 返回数据到FRED中 wQR0R~|M
