L9bIdiB7 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。
V|T3blG?D \0bZ1" 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:
iosL&*'8 enableservice('AutomationServer', true)
.NX>d@
Kc enableservice('AutomationServer')
OE8H |?%
Hphfqdh0` 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。
)K>2 r$/.x6g// 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:
A1kqWhg\ 1. 在FRED脚本编辑界面找到参考.
-MTO=#5z 2. 找到Matlab Automation Server Type Library
];7/DM#Np 3. 将名字改为MLAPP
48W-Tf6v| iTpK:pX RI0+9YJ 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。

&-B&s.,kj 3. 在探测面追迹
光线 (.J8Q 4. 在探测面计算
照度 .:?cU#. 5. 使用PutWorkspaceData发送照度数据到Matlab
h"849c;C. 6. 使用PutFullMatrix发送标量场数据到Matlab中
N^U<;O?YDW 7. 用Matlab画出照度数据
B>{\qj)% 8. 在Matlab计算照度平均值
{S=gXIh(y 9. 返回数据到FRED中
