hA)tad] 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。
~JY<DW7 Ie> )U)/$ 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:
.3k"1I
'\ enableservice('AutomationServer', true)
w^09|k enableservice('AutomationServer')
9 aT#7B
jJ-j 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。
ETe,RY CN0&uyu#4 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:
C,:3z 1. 在FRED脚本编辑界面找到参考.
"YD<pRVB 2. 找到Matlab Automation Server Type Library
4`uI)N(}* 3. 将名字改为MLAPP
?1 $.^ g]O"l?xx1D Kl~jcq&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。
5%C-eB 图 编辑/参考
-G2'c)DR (u@p[ncN} PNgj 8J4 现在将脚本代码公布如下,此脚本执行如下几个步骤:
jE_a++ 1. 创建Matlab服务器。
b8v?@s~ 2. 移动探测面对于前一聚焦面的位置。
rWI6L3,i+ 3. 在探测面追迹
光线 bJ~]nj 3 4. 在探测面计算
照度 1{R1:` 5. 使用PutWorkspaceData发送照度数据到Matlab
g&;:[&%T] 6. 使用PutFullMatrix发送标量场数据到Matlab中
hh`7b ,+ 4 7. 用Matlab画出照度数据
n
*|F=fl 8. 在Matlab计算照度平均值
,dK<2XP 9. 返回数据到FRED中
