[推荐]FRED案例-FRED如何调用Matlab [复制链接]

2N~E' 25  
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。 }t>q9bZ9z  
(\dK4JJ  
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： ACV ek  
enableservice('AutomationServer', true) qd!#t]  
    enableservice('AutomationServer') ?A7Yk4Y.?N  
6U,fz#<,}  
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。 y~F<9;$=

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： 5]7&IDA]]9  
1. 在FRED脚本编辑界面找到参考. )Hf~d=GG  
2. 找到Matlab Automation Server Type Library vN{-?  
    3. 将名字改为MLAPP C%ytk

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。 bj"z8kP

现在将脚本代码公布如下，此脚本执行如下几个步骤： =J@`0H"  
1. 创建Matlab服务器。 (BERY  
2. 移动探测面对于前一聚焦面的位置。 98*x 'Wp  
3. 在探测面追迹光线 x.EgTvA&d  
4. 在探测面计算照度 '1]7zWbW  
5. 使用PutWorkspaceData发送照度数据到Matlab St>`p-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 W3LP ~  
7. 用Matlab画出照度数据 bZ#X9fT  
8. 在Matlab计算照度平均值 >IR$e=5$  
9. 返回数据到FRED中
