b7~Jl+m 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。
$;Iz7:#jN ?E|=eO"I1 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:
Y&U-d{" enableservice('AutomationServer', true)
5dN>Xjpu enableservice('AutomationServer')
l5&5VC)
=N{?ll6x7g 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。
@fp@1n lX"m|W 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:
RLF6Bc 1. 在FRED脚本编辑界面找到参考.
jl(D;JnF 2. 找到Matlab Automation Server Type Library
h-;> v. 3. 将名字改为MLAPP
^L)3O|6c zuW4gJ -s`Wd4AP 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。

,Ww}xmq1H 3Wbd=^hRvq 4dCXBTT 现在将脚本代码公布如下,此脚本执行如下几个步骤:
F+Qnf'at1 1. 创建Matlab服务器。
hZL!%sL7 2. 移动探测面对于前一聚焦面的位置。
K{/i2^4 3. 在探测面追迹
光线 -Pt E+R[A 4. 在探测面计算
照度 z _\L@b 5. 使用PutWorkspaceData发送照度数据到Matlab
!-470J 6. 使用PutFullMatrix发送标量场数据到Matlab中
Xy 4k;+ 7. 用Matlab画出照度数据
)e`9U.C 8. 在Matlab计算照度平均值
xZ;eV76 9. 返回数据到FRED中
