[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。 #C3.Jef

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： &`XV
q"7  
enableservice('AutomationServer', true) >e"#'K0?\  
enableservice('AutomationServer') _ORvo{[:  
VU d\QR-  
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。 !GGkdg*-*9

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： b>N8F^}~O  
1. 在FRED脚本编辑界面找到参考. K6)j0]K1  
2. 找到Matlab Automation Server Type Library Ez=Olbk  
3. 将名字改为MLAPP UZsH9 o

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。 xK\

1. 创建Matlab服务器。 /gkX38  
2. 移动探测面对于前一聚焦面的位置。 3kMf!VL  
3. 在探测面追迹光线 3jC_AO%T  
4. 在探测面计算照度 /

5. 使用PutWorkspaceData发送照度数据到Matlab ,Vk3kmuvr]  
6. 使用PutFullMatrix发送标量场数据到Matlab中 #?9;uy<j.q  
7. 用Matlab画出照度数据 J~UuS+Ufv  
8. 在Matlab计算照度平均值 <yFu*(Q  
9. 返回数据到FRED中 `lt"[K<
