iYW<qgz 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。
1k%HGQM{ tI0D{Xrc 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:
dF&@q, enableservice('AutomationServer', true)
"-HWw?rx/ enableservice('AutomationServer')
T7Y+ WfYh
oB<!U%BN 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。
l>oJ^J '^Q$:P{G? 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:
e=!sMWx6 1. 在FRED脚本编辑界面找到参考.
*I9O63 2. 找到Matlab Automation Server Type Library
|*~SR.[` 3. 将名字改为MLAPP
eS%8WmCV9< HbCcROl( i\>?b)a> 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。

fndH]Yp 1. 创建Matlab服务器。
/.UISArH 2. 移动探测面对于前一聚焦面的位置。
}+:X= @Z@ 3. 在探测面追迹
光线 8qUNh# 4. 在探测面计算
照度 ayg^js2, 5. 使用PutWorkspaceData发送照度数据到Matlab
8y4t9V 6. 使用PutFullMatrix发送标量场数据到Matlab中
a 4?c~bs 7. 用Matlab画出照度数据
RRpCWcIv" 8. 在Matlab计算照度平均值
#=ko4?Wr( 9. 返回数据到FRED中
