[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。 X8 qIia

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： {\We72!  
enableservice('AutomationServer', true) YOw?'+8  
enableservice('AutomationServer') mTj
m92  
GXeAe}T  
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。 7*'@qjTos

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： YX;nMyD?~  
1. 在FRED脚本编辑界面找到参考. qX@9N=g`#O  
2. 找到Matlab Automation Server Type Library qY}Cg0[@g  
3. 将名字改为MLAPP Ar`\ N1a

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。 9.-47|-9C

现在将脚本代码公布如下，此脚本执行如下几个步骤： \^s2W:c  
1. 创建Matlab服务器。 5mIXyg 0:  
2. 移动探测面对于前一聚焦面的位置。 *H*\gaSh  
3. 在探测面追迹光线 }} #be  
4. 在探测面计算照度 A^vvST%7  
5. 使用PutWorkspaceData发送照度数据到Matlab "aA_(Ydzj  
6. 使用PutFullMatrix发送标量场数据到Matlab中 AA.Ys89V  
7. 用Matlab画出照度数据 &CO|Y(+  
8. 在Matlab计算照度平均值 \CwtX(6.  
9. 返回数据到FRED中 *
