1^}A 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。
cm]]9z_< ,jn?s^X6Dj 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:
X_qXH5^% enableservice('AutomationServer', true)
2
zy^(%a enableservice('AutomationServer')
Q@8[q l1l
Vo%d;>!G\; 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。
qEAF!iB]L ]VvJ1Xn0 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:
8syo_sC | 1. 在FRED脚本编辑界面找到参考.
|(SW 2. 找到Matlab Automation Server Type Library
R+K[/AA 3. 将名字改为MLAPP
{OOt+U! 8VZ-`?p <-F"&LI{< 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。

z+*Z<c5d 3. 在探测面追迹
光线

照度 (5> ibe 5. 使用PutWorkspaceData发送照度数据到Matlab
%\l,X{X 6. 使用PutFullMatrix发送标量场数据到Matlab中
`y`xk<q 7. 用Matlab画出照度数据
