[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。 VD).UdUn  
#+<"`}]N  
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： ar#Xe;T!  
enableservice('AutomationServer', true) Alh"ZT^*  
enableservice('AutomationServer') ! ,*4d $  
F79!B  
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。 M|l`2Hpe

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： }CoR$

1. 在FRED脚本编辑界面找到参考. L]_1z  
2. 找到Matlab Automation Server Type Library o2J-&   
3. 将名字改为MLAPP YgFmJ.1

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。 UF$JVb

现在将脚本代码公布如下，此脚本执行如下几个步骤： ]l~TI8gC  
1. 创建Matlab服务器。 z(yJ

2. 移动探测面对于前一聚焦面的位置。 &.ENcEic  
3. 在探测面追迹光线 {okx*]PIc  
4. 在探测面计算照度 SMMsXH  
5. 使用PutWorkspaceData发送照度数据到Matlab jEkO#xI  
6. 使用PutFullMatrix发送标量场数据到Matlab中 R}S@u@mOE  
7. 用Matlab画出照度数据 Rb8wq.LqD  
8. 在Matlab计算照度平均值 6H)T=Z|  
9. 返回数据到FRED中 X,Q'Xe/
