99xs5!4s 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。
K
chp% +@n8DM{b 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:
bLSZZfq enableservice('AutomationServer', true)
hT
c
VMc enableservice('AutomationServer')
6I5,PB
km%c0: 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。
/Mac:;W` l'Oz-p.@ 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:
Zq,[se'nh" 1. 在FRED脚本编辑界面找到参考.
uL.)+E 2. 找到Matlab Automation Server Type Library
l+%2kR 3. 将名字改为MLAPP
LYYz =gvZl ;"d>lyL V5]}b[X 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。

QL_vWG- 1. 创建Matlab服务器。
LIm{Y`XU 2. 移动探测面对于前一聚焦面的位置。
tBJCfM 3. 在探测面追迹
光线 n\X'2 4. 在探测面计算
照度 H%`$@U> 5. 使用PutWorkspaceData发送照度数据到Matlab
uItzFX* 6. 使用PutFullMatrix发送标量场数据到Matlab中
