[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。 8`B3;Zmm  
q.^;!f1  
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： ^+>laOzC`8  
enableservice('AutomationServer', true) @su^0 9n  
enableservice('AutomationServer') O'p9u@kc  
T"}5}6rSG  
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。 O_muD\

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： ed{ -/l~j  
1. 在FRED脚本编辑界面找到参考.
c(f  
2. 找到Matlab Automation Server Type Library ~]|6T~+]83  
3. 将名字改为MLAPP 4<w.8rR:A

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。 )5Q~I,dP

现在将脚本代码公布如下，此脚本执行如下几个步骤： hohfE3rd  
1. 创建Matlab服务器。 Fbr;{T .
 
2. 移动探测面对于前一聚焦面的位置。 h9&0Z+zs  
3. 在探测面追迹光线 a{'vN93  
4. 在探测面计算照度 hlvK5Z  
5. 使用PutWorkspaceData发送照度数据到Matlab <Uk}o8E  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ]Grek<  
7. 用Matlab画出照度数据 s0TORl6Z|  
8. 在Matlab计算照度平均值 RtkEGxw*^  
9. 返回数据到FRED中 WH#1zv
