"/R?XCBZsb 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。
`@y~ JNf! HL{aqT2 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:
DlzL(p@r enableservice('AutomationServer', true)
K-'uE) enableservice('AutomationServer')
>_Tyzl>z
|K.I%B 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。
~vYFQKrb ` 0@m, 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:
Lum=5zDo 1. 在FRED脚本编辑界面找到参考.
p4uzw 2. 找到Matlab Automation Server Type Library
\>\ERVEd 3. 将名字改为MLAPP
:"y2u %]F/!n WReHep 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。
$\m:}\%p 图 编辑/参考

%S%UMA. 1. 创建Matlab服务器。
qbc= kP 2. 移动探测面对于前一聚焦面的位置。
{yNeZXA> 3. 在探测面追迹
光线 l>|scs;TI 4. 在探测面计算
照度 zSA"f_e 5. 使用PutWorkspaceData发送照度数据到Matlab
sC"w{_D@*4 6. 使用PutFullMatrix发送标量场数据到Matlab中
\E c*Gq?. 7. 用Matlab画出照度数据
,]t_9B QK 8. 在Matlab计算照度平均值
LmY[{.'tX 9. 返回数据到FRED中
