[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。 Ry47Fze  
*A<vrkHz  
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： zWs("L(#s  
enableservice('AutomationServer', true) g&E3Wc  
enableservice('AutomationServer') 2Dc2uU@`r

8<Z=#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。 azK7kM~

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： 0H9UM*O  
1. 在FRED脚本编辑界面找到参考. dG8_3T}i  
2. 找到Matlab Automation Server Type Library r`dQ<U,  
3. 将名字改为MLAPP k-V3l

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。 .}n-N #

现在将脚本代码公布如下，此脚本执行如下几个步骤： Q9G\T:^ury  
1. 创建Matlab服务器。 -v@LJCK7I  
2. 移动探测面对于前一聚焦面的位置。 s(.H"_a  
3. 在探测面追迹光线 {s7 3(B"  
4. 在探测面计算照度 " ""k}M2A  
5. 使用PutWorkspaceData发送照度数据到Matlab mz>GbImVD~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 o=]\Jy  
7. 用Matlab画出照度数据 !VDNqW  
8. 在Matlab计算照度平均值 Be$v%4  
9. 返回数据到FRED中  `1`Qu!
