~H:.&'E 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。
hR,5U=+M7 &%4A3.qE 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:
EMf"rGXu( enableservice('AutomationServer', true)
Hv</Xam enableservice('AutomationServer')
sOm&7A?
{-51rAyi 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。

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:
^TT_BAI 1. 在FRED脚本编辑界面找到参考.
}'4aW_ta 2. 找到Matlab Automation Server Type Library
3-gy)5.xe 3. 将名字改为MLAPP
F6Qnz8| [_HOD^ cG!dMab( 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。

a 1. 创建Matlab服务器。
*z__$!LR 2. 移动探测面对于前一聚焦面的位置。
`%$+rbo~ 3. 在探测面追迹
光线 1SG^X-(GM/ 4. 在探测面计算
照度 hs<OzM
5. 使用PutWorkspaceData发送照度数据到Matlab
eV\VR
!!i 6. 使用PutFullMatrix发送标量场数据到Matlab中
R0T{9,;[` 7. 用Matlab画出照度数据
cG5u$B 8. 在Matlab计算照度平均值
Wux[h8G
9. 返回数据到FRED中
