[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。 #a'r_K=ch)  
c=aO5(i0  
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： Yv=g^tw
  
enableservice('AutomationServer', true) wASX\D }  
enableservice('AutomationServer') $+jy/:]D  
#Cx%OIi[f  
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。 G

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： ZB0+GG\  
1. 在FRED脚本编辑界面找到参考. R[Nbtbv9Q  
2. 找到Matlab Automation Server Type Library I=odMw7Hj  
3. 将名字改为MLAPP GW8CaTf~

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。 D )gD<

现在将脚本代码公布如下，此脚本执行如下几个步骤： ,Z5Fea  
1. 创建Matlab服务器。 ^/<|f,2  
2. 移动探测面对于前一聚焦面的位置。 sUV>@UMnu  
3. 在探测面追迹光线 LuL$v+`  
4. 在探测面计算照度 Ro~fvL~Ps  
5. 使用PutWorkspaceData发送照度数据到Matlab y@aKNWy}$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 v#F-<?Vv  
7. 用Matlab画出照度数据 ll2Vk*xs  
8. 在Matlab计算照度平均值 Man^<T%F  
9. 返回数据到FRED中 Khap9a_q-
