[cJQ"G ' 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。
6snDv4 |\HYq`!g%7 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:
A%Ov.~&\G enableservice('AutomationServer', true)
`2WtA_ enableservice('AutomationServer')
[_$r- FA
?(C(9vO 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
+jpaBr-O# 7!-3jU@m 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
#sHA!@ | 1. 在FRED脚本编辑界面找到参考.
f82$_1s^ 2. 找到Matlab Automation Server Type Library
[{s 1=c 3. 将名字改为MLAPP
} kNbqwVP JpI(Vcd $ 12mS 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。

XwZ~pY ~ 1. 创建Matlab服务器。
$q"/q*ys 2. 移动探测面对于前一聚焦面的位置。
E$u9Jbe 3. 在探测面追迹
光线 `5HFRgL`. 4. 在探测面计算
照度 $A4rdhvd 5. 使用PutWorkspaceData发送照度数据到Matlab
_oV;Y`_ 6. 使用PutFullMatrix发送标量场数据到Matlab中
G<F+/Oi&DX 7. 用Matlab画出照度数据
5g x9W\a ? 8. 在Matlab计算照度平均值
L9lN AiOH 9. 返回数据到FRED中
