.Pte}pM"v 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。
Ziub%C[oV [}GK rI 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:
O9o ]4; enableservice('AutomationServer', true)
](8F]J , enableservice('AutomationServer')
ggitUQ+t;G
b62B|0i 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。
om9'A=ZU FC6~V6R 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:
$~/cxLcT 1. 在FRED脚本编辑界面找到参考.
Iz-mUD0; 2. 找到Matlab Automation Server Type Library
#qR 6TM&; 3. 将名字改为MLAPP
PB.'huu 7fO<=ei: @V:Y%#% 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。

_dz ZS(7M6 ?*yB&(a:8 7:Rt) EE2 现在将脚本代码公布如下,此脚本执行如下几个步骤:
C984Ee 1. 创建Matlab服务器。
0!KYi_3 2. 移动探测面对于前一聚焦面的位置。
I1l^0@J 3. 在探测面追迹
光线 tg==Qgz 4. 在探测面计算
照度 GoAh{=s 5. 使用PutWorkspaceData发送照度数据到Matlab
`-{? ! 6. 使用PutFullMatrix发送标量场数据到Matlab中
SdYbT)y 7. 用Matlab画出照度数据
^);M}~ 8. 在Matlab计算照度平均值
|HYST` 9. 返回数据到FRED中
