U'3Fou} 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。
-l.pA(O ZzL@[g 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:
-Z?Ck!00 enableservice('AutomationServer', true)
Lbq_~ enableservice('AutomationServer')
$j`<SxJ>
)W9_qmYd" 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
-^fzsBL. ic~Z_?p 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
^HFo3V
}h 1. 在FRED脚本编辑界面找到参考.
QAaF@Do 2. 找到Matlab Automation Server Type Library
c/$*%J< 3. 将名字改为MLAPP
t.z$j _bQL[eXd 6D*chvNA; 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。

RSH/l;ii 1. 创建Matlab服务器。
!1-&Y'+ 2. 移动探测面对于前一聚焦面的位置。
[#X|+M&u6 3. 在探测面追迹
光线 v!!;js^ 4. 在探测面计算
照度 T 'i~_R6 5. 使用PutWorkspaceData发送照度数据到Matlab
1#!@[" 6. 使用PutFullMatrix发送标量场数据到Matlab中
T:#S86m 7. 用Matlab画出照度数据
/Su)|[/' 8. 在Matlab计算照度平均值
^n71'MW 9. 返回数据到FRED中
