=w<iYO 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。
%}unlSTPP \w-3Spk* 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:
'-#gQxIpD enableservice('AutomationServer', true)
h7S;
4] enableservice('AutomationServer')
aM:tg1g
e~nh95 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。
^ '_Fd hTPvt 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:
aHPx'R 1. 在FRED脚本编辑界面找到参考.
[a.(0YLr'w 2. 找到Matlab Automation Server Type Library
"&\(:#L 3. 将名字改为MLAPP
~/Y8wxg )iZhE"?z S+?*l4QK 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。

24fN3 现在将脚本代码公布如下,此脚本执行如下几个步骤:
8jiBLZkRf 1. 创建Matlab服务器。
xscR Bx 2. 移动探测面对于前一聚焦面的位置。
"V,dH%&j 3. 在探测面追迹
光线 ^}kYJvqA 4. 在探测面计算
照度 iphdJZ/f 5. 使用PutWorkspaceData发送照度数据到Matlab
@?</8;%3W 6. 使用PutFullMatrix发送标量场数据到Matlab中
z;>O5a>z 7. 用Matlab画出照度数据
#XNURj 8. 在Matlab计算照度平均值
NkQain9 9. 返回数据到FRED中
