O 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。
>$Y/B=e bWSN]]e1# 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:
>oh Cz@~ enableservice('AutomationServer', true)
N8A)lYT]_u enableservice('AutomationServer')
qxZIH
"*vrrY 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。
9a`LrB }'[>~&/" 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:
4uF.kz-cg 1. 在FRED脚本编辑界面找到参考.
:saP
:& 2. 找到Matlab Automation Server Type Library
W>3S%2d 3. 将名字改为MLAPP
LV}R 9f U`v2Yw3E -wU]L5uP 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。

j~v`q5X 1. 创建Matlab服务器。
d/_D|ivZ= 2. 移动探测面对于前一聚焦面的位置。
GRZz@bAO?$ 3. 在探测面追迹
光线 b.*LmSX# 4. 在探测面计算
照度 v9(5HY 5. 使用PutWorkspaceData发送照度数据到Matlab
