5O& 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。
,&A7iO 8Al{+gx@? 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:
P;.W+WN enableservice('AutomationServer', true)
^LnTOdAE enableservice('AutomationServer')
g/d<Zfq<{
#lo6c;*m5 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。
6Igz:eX 2QcOR4_V 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:
5DU6rks% 1. 在FRED脚本编辑界面找到参考.
#P9~}JB3, 2. 找到Matlab Automation Server Type Library
rgQOj^xKv^ 3. 将名字改为MLAPP
NN{?z! eb{nWP )AtD}HEv 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。

{w O|)| 1. 创建Matlab服务器。
Mx ?d 2. 移动探测面对于前一聚焦面的位置。
k

光线 %IA\pSE 4. 在探测面计算
照度 ?zMHP#i 5. 使用PutWorkspaceData发送照度数据到Matlab
7aRi5 6. 使用PutFullMatrix发送标量场数据到Matlab中
O:R*rJ 7. 用Matlab画出照度数据
Et_bH%0 8. 在Matlab计算照度平均值
Mj3A5;# 9. 返回数据到FRED中
