wzB*M}3 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。
W;*rSK|(Sc PPT"?lt*& 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:
Oy[1_qfP enableservice('AutomationServer', true)
l(9$s4R enableservice('AutomationServer')
v'*Q[
('
^pMjii8IZ 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
phSF.WC !_s|h@ 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
&|P@$O> 1. 在FRED脚本编辑界面找到参考.
wJh|$Vn 2. 找到Matlab Automation Server Type Library
HTI1eLZ2 3. 将名字改为MLAPP
ke|v|@ UC^&&
2maI %JDG aG' 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。

WZ5[tZf 1. 创建Matlab服务器。
k|-`d 2. 移动探测面对于前一聚焦面的位置。
?RvXO'm l 3. 在探测面追迹
光线 Z$0r+phQk= 4. 在探测面计算
照度 z
h0 m3|9O 5. 使用PutWorkspaceData发送照度数据到Matlab
I#@iA! 6. 使用PutFullMatrix发送标量场数据到Matlab中
"^gZh3 7. 用Matlab画出照度数据
+V1EqC* 8. 在Matlab计算照度平均值
,5'LbO- 9. 返回数据到FRED中
