f 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。
7|ACJv6%9 vvG*DGL)qL 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:
Yv{$XI7 enableservice('AutomationServer', true)
'OhGSs| enableservice('AutomationServer')
>^@~}]L
_lH:%E* 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。
7/=r- UY\E uA9 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:
@9]TjZd 1. 在FRED脚本编辑界面找到参考.
4Dd]:2|D 2. 找到Matlab Automation Server Type Library
}&l%>P 3. 将名字改为MLAPP
/I`- >#;>6q9_ K9RRY,JB 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。
7;#o?6!7 图 编辑/参考
zb!RfQ, JVx-4? );p:[=$71 现在将脚本代码公布如下,此脚本执行如下几个步骤:
cGg~+R2P 1. 创建Matlab服务器。
+=kz".$ 2. 移动探测面对于前一聚焦面的位置。
ZoqE,ucH 3. 在探测面追迹
光线 .g_Kab3?L 4. 在探测面计算
照度 Wjd_|Kui 5. 使用PutWorkspaceData发送照度数据到Matlab
wX@g>( 6. 使用PutFullMatrix发送标量场数据到Matlab中
PC?XE8o 7. 用Matlab画出照度数据
A22'qgKm@ 8. 在Matlab计算照度平均值
B1U7z1< 9. 返回数据到FRED中
