[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。 Lg

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： yS:1F PA$_  
enableservice('AutomationServer', true) Z<0+<tt  
enableservice('AutomationServer') 5&*B2ZBzH  
ewcgg  
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。 HR83{B21

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： ,0Y5O?pu\  
1. 在FRED脚本编辑界面找到参考. NQ(}rr'.  
2. 找到Matlab Automation Server Type Library *!y.!v*  
3. 将名字改为MLAPP .8%mi'0ud

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。 U)N_/

现在将脚本代码公布如下，此脚本执行如下几个步骤： rpT{0>5  
1. 创建Matlab服务器。 |O]oX[~  
2. 移动探测面对于前一聚焦面的位置。 MrA&xM  
3. 在探测面追迹光线 7+I

4. 在探测面计算照度 &`'gO 9  
5. 使用PutWorkspaceData发送照度数据到Matlab ^L<*ggw  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?=uw0~O[  
7. 用Matlab画出照度数据 k98}Jx7J)"  
8. 在Matlab计算照度平均值 XHlx89v7  
9. 返回数据到FRED中 [af<FQ{
