[推荐]FRED案例-FRED如何调用Matlab [复制链接]

v7\~OOoH]  
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。 +)qPUKb?

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：
!Z<GUblt  
enableservice('AutomationServer', true) .Xg%><{~  
    enableservice('AutomationServer') ygd'Nh!@  
XqyfeY5t  
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。 L&Qdb xn

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： YM1tP'4j@  
1. 在FRED脚本编辑界面找到参考. BYhPOg[  
2. 找到Matlab Automation Server Type Library g5M-Vu  
    3. 将名字改为MLAPP o//N"S.)

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。 0Dc$nL?TqX

1. 创建Matlab服务器。 k#5S'sCF<  
2. 移动探测面对于前一聚焦面的位置。 8:huWjh]M  
3. 在探测面追迹光线 qdAz3iye  
4. 在探测面计算照度 KG4~t=J`  
5. 使用PutWorkspaceData发送照度数据到Matlab aS'G&(_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vJtQ&,zG  
7. 用Matlab画出照度数据 l!~8  
8. 在Matlab计算照度平均值 *xkbKkm  
9. 返回数据到FRED中 G"O%u|7
