0gn@h/F2% 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。
=]>NDWqpHN vwr74A.g0 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:AkkkF enableservice('AutomationServer', true)
z1!6%W_. enableservice('AutomationServer')
;_:Oo l,
IAOcKQ3 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。
RA jkH` WM)F0@" 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:
K{l5m{:% 1. 在FRED脚本编辑界面找到参考.
?/JBt
/b 2. 找到Matlab Automation Server Type Library
w&BGJYI 3. 将名字改为MLAPP
`E\imL %k0EpJE% R1-k3;v^ 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。

g8'DoHJ* 1. 创建Matlab服务器。
jFerYv&K~ 2. 移动探测面对于前一聚焦面的位置。
m/`IGT5J 3. 在探测面追迹
光线 Be}$I_95\P 4. 在探测面计算
照度 jvzBh-! 5. 使用PutWorkspaceData发送照度数据到Matlab
zEw>SP1, 6. 使用PutFullMatrix发送标量场数据到Matlab中
{ ?{U,& 7. 用Matlab画出照度数据
PzY)"]g 8. 在Matlab计算照度平均值
@1R8-aa-r 9. 返回数据到FRED中
