T}} 0hs; 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。
z _qy> g8^\| 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:
w-2&6o<n- enableservice('AutomationServer', true)
mF!/8qk enableservice('AutomationServer')
)aoB-Lu
Z(Da?6#1 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。
zNSix!F V]b1cDx{ 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:
5.gM]si 1. 在FRED脚本编辑界面找到参考.
m-f"EFmP 2. 找到Matlab Automation Server Type Library
csn/h$`-@ 3. 将名字改为MLAPP
q6A!xQs< R=M"g|U6 m"Y;GzqQl 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。

xdWfrm$;ZA 1. 创建Matlab服务器。
\PS{/XK 2. 移动探测面对于前一聚焦面的位置。
'Cy^G; 3. 在探测面追迹
光线 1*S5:7Tb 4. 在探测面计算
照度 xe^*\6Y 5. 使用PutWorkspaceData发送照度数据到Matlab
CU=}]Y 6. 使用PutFullMatrix发送标量场数据到Matlab中
!:e|M|T'I* 7. 用Matlab画出照度数据
`|K,E 8. 在Matlab计算照度平均值
4)D#kP 9. 返回数据到FRED中
