!X5LgMw^ ; 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。
c(kYCVc Ez/>3:; 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:
zNO,vR[\ enableservice('AutomationServer', true)
)Z*nm<= enableservice('AutomationServer')
M?d (-en
*`_2uBz 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。
S l`F` ~<Z7\yS) 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:
aKFY&zN? 1. 在FRED脚本编辑界面找到参考.
tZ.hSDH 2. 找到Matlab Automation Server Type Library
S^x?<kYQau 3. 将名字改为MLAPP
V"|`Z}XW YO9ofT aH&Efz^ 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。

hRNnj 1. 创建Matlab服务器。
`)tIXMn 2. 移动探测面对于前一聚焦面的位置。
Zg4kO;r08 3. 在探测面追迹
光线 sE])EwZ 4. 在探测面计算
照度 O'{g{ 5. 使用PutWorkspaceData发送照度数据到Matlab
z[qi~&7:v 6. 使用PutFullMatrix发送标量场数据到Matlab中
1=_Qj}!1 7. 用Matlab画出照度数据
Eq=j+ch7 8. 在Matlab计算照度平均值
Ie[DTy 9. 返回数据到FRED中
