=jJEl=*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。
G %6P`: z8'1R6nq 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:
6oNcj_?7?q enableservice('AutomationServer', true)
>
:IWRc2 enableservice('AutomationServer')
{VL@U$'oI
!6T"J!F# 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
-g]Rs!w' <ZF|2 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
#uw&u6*\q 1. 在FRED脚本编辑界面找到参考.
8s@N NjV 2. 找到Matlab Automation Server Type Library
k=hWYe$iAz 3. 将名字改为MLAPP
Z0jgUq`r 12KC4,C&1i 0(D^NtB7 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。

y)b`r 现在将脚本代码公布如下,此脚本执行如下几个步骤:
kkF)Tro\ 1. 创建Matlab服务器。
>sfg`4 2. 移动探测面对于前一聚焦面的位置。
{P]C> 3. 在探测面追迹
光线 }OL"38P 4. 在探测面计算
照度 N8b\OTk2 5. 使用PutWorkspaceData发送照度数据到Matlab
xi=ApwNj 6. 使用PutFullMatrix发送标量场数据到Matlab中
kg[%Q]] 7. 用Matlab画出照度数据
`za,sRFR 8. 在Matlab计算照度平均值
CwA_jOp 9. 返回数据到FRED中
