U%q7Ai7 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。
60J;sGW 18+)`M-5o 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:
`(_s|-$ enableservice('AutomationServer', true)
E\as@pqo\p enableservice('AutomationServer')
WtG~('g>&
wr$M$i: 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。
bN]+_ mF C8Qa$._ 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:
F'4w;-ax 1. 在FRED脚本编辑界面找到参考.
bpH^:fyLU` 2. 找到Matlab Automation Server Type Library
c:<005\Bg 3. 将名字改为MLAPP
Y2n!>[[. fI{&#~f4C M>~Drul 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。

++6`sMJ 1. 创建Matlab服务器。
6kpg+{; 2. 移动探测面对于前一聚焦面的位置。
1*'HL# 3. 在探测面追迹
光线 nExU#/*~^ 4. 在探测面计算
照度 u%}nw :> 5. 使用PutWorkspaceData发送照度数据到Matlab
D^l%{IG

g!lWu[d 7. 用Matlab画出照度数据

W+UfGk}A 9. 返回数据到FRED中
