JE*d- 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。
;xl0J*r Q;xJ/4 Z" 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:
{44#<A< enableservice('AutomationServer', true)
Nrn_Gy>|D enableservice('AutomationServer')
z@21Z`,
lS96Z3k"SB 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。
PNs*+/-S jAcrXB* 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:
! }>CEE 1. 在FRED脚本编辑界面找到参考.
0sA+5*mdM 2. 找到Matlab Automation Server Type Library
S0'
ACt` 3. 将名字改为MLAPP
rQD^O4j R FTQNS8 M-8`zA2 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。

h5Ee*De 2. 移动探测面对于前一聚焦面的位置。
H:F'5Zt 3. 在探测面追迹
光线 9vauCIfVC 4. 在探测面计算
照度 RuGG3"| 5. 使用PutWorkspaceData发送照度数据到Matlab
CUN1.i<pk8 6. 使用PutFullMatrix发送标量场数据到Matlab中
d.0K~M 7. 用Matlab画出照度数据
(6* 8. 在Matlab计算照度平均值
]5r@`%9 9. 返回数据到FRED中
