@2 fg~2M1 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。
fmDCP kj ^3L0w}# 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:
v,>Dbxn enableservice('AutomationServer', true)
I4i>+:_J enableservice('AutomationServer')
j+
0I-p
o:Sa,
!DK 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。
#'9HU2 -C?ZB}` 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:
?+}_1x` 1. 在FRED脚本编辑界面找到参考.
eV?2LtT#5 2. 找到Matlab Automation Server Type Library
y/ef>ZZ 3. 将名字改为MLAPP
O[JL+g4
[:SWi1cK2 4u})+2W 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。

n[Y~] 1. 创建Matlab服务器。
ZeaA%y67U 2. 移动探测面对于前一聚焦面的位置。
cB}D^O 3. 在探测面追迹
光线 fHd#u%63K 4. 在探测面计算
照度 mSl.mi(JiZ 5. 使用PutWorkspaceData发送照度数据到Matlab
;,:`1UI 6. 使用PutFullMatrix发送标量场数据到Matlab中
N~zdWnSZ@G 7. 用Matlab画出照度数据
