h8 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。
S/7l/DFb I .P6l*$ 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:
ISBF\ wQY enableservice('AutomationServer', true)
*)D1!R<\,R enableservice('AutomationServer')
>f@ G>H)+
]2$x|#Gg} 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
fEwifSp. Sc_5FX\Yx 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
`tVy_/3(9 1. 在FRED脚本编辑界面找到参考.
V;;#/$oU:4 2. 找到Matlab Automation Server Type Library
.&|L|q} 3. 将名字改为MLAPP
(O0byu} NzlAC v2>Z^ 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。

]0-<> 1. 创建Matlab服务器。
YlKFw|= 2. 移动探测面对于前一聚焦面的位置。
D/:3RZF 3. 在探测面追迹
光线 `eD1|Go9 4. 在探测面计算
照度 5v|EAjB6o 5. 使用PutWorkspaceData发送照度数据到Matlab
b-%l-u 6. 使用PutFullMatrix发送标量场数据到Matlab中
K*+6`z#fMF 7. 用Matlab画出照度数据
L!y"d!6C 8. 在Matlab计算照度平均值
;4kT?3$l 9. 返回数据到FRED中
