n2Ew0- 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。
X~Hm.qIR .HPa\b\L> 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:
4mnVXKt%. enableservice('AutomationServer', true)
J>1%*Tz enableservice('AutomationServer')
o^b5E=?>C
b;5
M$
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。
GIhFOK m+xub*/ 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:
2IXtIE 1. 在FRED脚本编辑界面找到参考.
n_kE 2. 找到Matlab Automation Server Type Library
L9d|7.b 3. 将名字改为MLAPP
A+(+PfU \s7/` Jv?EV,S/e 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。

H0b 现在将脚本代码公布如下,此脚本执行如下几个步骤:
W=Mdh}u_I 1. 创建Matlab服务器。
?0+N 2. 移动探测面对于前一聚焦面的位置。
uzIM?.H 3. 在探测面追迹
光线 H\$uRA oo* 4. 在探测面计算
照度 AOef1^S= 5. 使用PutWorkspaceData发送照度数据到Matlab
:KS"&h{ SY 6. 使用PutFullMatrix发送标量场数据到Matlab中
c[Z#q*Q 7. 用Matlab画出照度数据
Vze vOS 8. 在Matlab计算照度平均值
GU]kgwSfi 9. 返回数据到FRED中
