$-73}[UA 4 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。
pz+#1=b] |.5d ^z 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:
IT|CfQ [D enableservice('AutomationServer', true)
X,~C enableservice('AutomationServer')
+,,~<Vm
3(kZfH~ 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。
*v&RGY[> F2=97=R 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:
zF7T5Ge 1. 在FRED脚本编辑界面找到参考.
=1C9lKm 2. 找到Matlab Automation Server Type Library
sXA=KD8 3. 将名字改为MLAPP
?fGY,<c 9L,T @#7 6*tGf`Pfdw 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。

O#g31?TO 1. 创建Matlab服务器。
1ARIZ;H 2. 移动探测面对于前一聚焦面的位置。
utv.uwfat 3. 在探测面追迹
光线 V!p;ME 4. 在探测面计算
照度 f|!zjX` 5. 使用PutWorkspaceData发送照度数据到Matlab
8}2
`^<U 6. 使用PutFullMatrix发送标量场数据到Matlab中
oID,PB*9 7. 用Matlab画出照度数据
~p&sd) 8. 在Matlab计算照度平均值
3 }XS|Y 9. 返回数据到FRED中
