J#0GlK@" 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。
kGpV;F==* plK=D#) 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:
pJd 0k"{ enableservice('AutomationServer', true)
:bwM]k*$ enableservice('AutomationServer')
?$3r5sx
6^Ph ' 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。
VJ3hC[ +W6Hva. 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:
;P3>>DZ 1. 在FRED脚本编辑界面找到参考.
#e*X0;m 2. 找到Matlab Automation Server Type Library
j8pFgnQ 3. 将名字改为MLAPP
fCB:733H 8)sg_JC C*7!dW6 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。

F<5nGx cC 1. 创建Matlab服务器。
)!cI|tovs 2. 移动探测面对于前一聚焦面的位置。
|=\91fP68` 3. 在探测面追迹
光线 .8]Y- 4. 在探测面计算
照度 X:Q$gO?[4 5. 使用PutWorkspaceData发送照度数据到Matlab
s|Zx(.EP 6. 使用PutFullMatrix发送标量场数据到Matlab中
jPnO@H1 7. 用Matlab画出照度数据
fE^uF[-7? 8. 在Matlab计算照度平均值
B
