[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。 crJNTEz  
G }M!  
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： mG%cE(j*D  
enableservice('AutomationServer', true) ^.M_1$-  
enableservice('AutomationServer') Y5TBWcGU%  
7N0m7SC  
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。 7KtgR=-Lb

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： we?t/YB=  
1. 在FRED脚本编辑界面找到参考. ">s0B5F7  
2. 找到Matlab Automation Server Type Library *T{KpiuP  
3. 将名字改为MLAPP |\]pTA$2

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。 eoPoG

现在将脚本代码公布如下，此脚本执行如下几个步骤： o#IWH;ck.  
1. 创建Matlab服务器。 /`w'X/'VJ  
2. 移动探测面对于前一聚焦面的位置。 ND5E`Va5R  
3. 在探测面追迹光线 ,aa %{  
4. 在探测面计算照度 4;w#mzd  
5. 使用PutWorkspaceData发送照度数据到Matlab .|K\1qGW0  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8
7nsWBe  
7. 用Matlab画出照度数据 dRTpG
z  
8. 在Matlab计算照度平均值 U9AtC.IG!  
9. 返回数据到FRED中 (7v`5|'0
