U,%s; 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。
hV3,^#9o dJdD"xj 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:
]97Xu_ enableservice('AutomationServer', true)
26\HV enableservice('AutomationServer')
L?3VyBE
$?]@_= 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。
_qC+'RE3 W; 3
R; 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:
_%A/ ) 1. 在FRED脚本编辑界面找到参考.
`!Ua ScM 2. 找到Matlab Automation Server Type Library
u4Y6B
]Q 3. 将名字改为MLAPP
".~MmF {Ior.(D>Y !XgQJ7y_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。

>VRo|o<D 1. 创建Matlab服务器。
*fxep08B 2. 移动探测面对于前一聚焦面的位置。
&q," !:L] 3. 在探测面追迹
光线 g6rv`I$l 4. 在探测面计算
照度 p&k0Rx0Q3 5. 使用PutWorkspaceData发送照度数据到Matlab
BlkSWW/ 6. 使用PutFullMatrix发送标量场数据到Matlab中
bh= \ 7. 用Matlab画出照度数据
vqrBRlZ 8. 在Matlab计算照度平均值
E0sbU<11 9. 返回数据到FRED中
