pKL^<'w0 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。
g;nPF*( @rW%*?$7 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
}PzYt~Z`@ enableservice('AutomationServer', true)
l0wvWv*k enableservice('AutomationServer')
_@]@&^K$E
P4"EvdV7 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。

Tw J$Ba*`~!! 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:
s9YP
=)I 1. 在FRED脚本编辑界面找到参考.
IPh_QE2g 2. 找到Matlab Automation Server Type Library
WkY>--^ 3. 将名字改为MLAPP
#kEa&Se ;Q8rAsf9 <+7-^o_ 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。

SJI+$L\' cW, 6MAQo b"#|0d0 现在将脚本代码公布如下,此脚本执行如下几个步骤:
Qte'f+ 1. 创建Matlab服务器。
D\GP+Ota 2. 移动探测面对于前一聚焦面的位置。
Y]1b39O 3. 在探测面追迹
光线 A?OaP 4. 在探测面计算
照度 tB{O6=q 5. 使用PutWorkspaceData发送照度数据到Matlab
n&uD=- 6. 使用PutFullMatrix发送标量场数据到Matlab中
R*psL&N 7. 用Matlab画出照度数据
0~N2MoOl^ 8. 在Matlab计算照度平均值
(/l9@0Y.t 9. 返回数据到FRED中
