[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。 *S.U8;*Xj  
l[/`kK  
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： ;,&cWz  
enableservice('AutomationServer', true) MVYd\)\o  
enableservice('AutomationServer') 1r;zA<<%R  
5'} V`?S  
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。 bF"l0 jS

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： X;I9\Cp]!  
1. 在FRED脚本编辑界面找到参考. 9ddrtJ]  
2. 找到Matlab Automation Server Type Library p%Z:SZZ  
3. 将名字改为MLAPP %j7b0pb

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。 G*CPj^O

现在将脚本代码公布如下，此脚本执行如下几个步骤： c7e,lgG-  
1. 创建Matlab服务器。 SI}s  
2. 移动探测面对于前一聚焦面的位置。 %O"8|ZG9{  
3. 在探测面追迹光线 PF%-fbh!~  
4. 在探测面计算照度 2e`}

5. 使用PutWorkspaceData发送照度数据到Matlab &`r/+B_W  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _'=,c"  
7. 用Matlab画出照度数据 FZHA19Kb  
8. 在Matlab计算照度平均值 JVc{vSa!rm  
9. 返回数据到FRED中 [l23b{
