[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。 u8@>ThPD  
doaqHri\,  
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： _qqJ>E<0  
enableservice('AutomationServer', true) l,3[hx  
enableservice('AutomationServer') uw@|Y{(K r  
Yt;.Z$i ,  
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。 -n~VMLd?@

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： n-_-

1. 在FRED脚本编辑界面找到参考. Djf,#&j!3  
2. 找到Matlab Automation Server Type Library ouUU(jj02  
3. 将名字改为MLAPP 3^zOG2

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。 Gwkp(

1. 创建Matlab服务器。 Wz7jB6AWA  
2. 移动探测面对于前一聚焦面的位置。 zKk2>.  
3. 在探测面追迹光线 [e'Ts#($A  
4. 在探测面计算照度 )/9/p17:xu  
5. 使用PutWorkspaceData发送照度数据到Matlab s0"1W"7vh  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?o9g5Z  
7. 用Matlab画出照度数据 Rj=xn(@d  
8. 在Matlab计算照度平均值 Tce2]"^;  
9. 返回数据到FRED中 Ol24A^
