9ZDVy7m\i- 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。
n1QEu"~Zj ePp[m
zg6 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:
J| SwQE~ enableservice('AutomationServer', true)
3ty4D 2y enableservice('AutomationServer')
dqqnCXYuW
F:M>z= 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。
R'6@n#: EXA^!/) 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:
wgY6D!Y 1. 在FRED脚本编辑界面找到参考.
TC qkm^xv 2. 找到Matlab Automation Server Type Library
7:n?PN(p6a 3. 将名字改为MLAPP
In
f9wq\ i[$-_ sYGR-:K 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。

fO K|: 1. 创建Matlab服务器。
Da-u-_~ 2. 移动探测面对于前一聚焦面的位置。
glv ;C/l 3. 在探测面追迹
光线 9Ei5z6Vk/+ 4. 在探测面计算
照度 Le*`r2 5. 使用PutWorkspaceData发送照度数据到Matlab
gs?8Wzh90* 6. 使用PutFullMatrix发送标量场数据到Matlab中
/@VsqD 7. 用Matlab画出照度数据
8tU>DJ}0 8. 在Matlab计算照度平均值
d]U`?A, 9. 返回数据到FRED中
