[英]Example data sets in Matlab
There are several example data sets in Matlab, for example wind and mri . Matlab中有几个示例数据集,例如wind和mri 。 If you execute the command
load wind
you will load the data in the data set wind . 如果执行命令
load wind
,则将加载数据集wind中的数据。 Some are included in toolboxes and some appear to be included in standard Matlab. 有些包含在工具箱中,有些似乎包含在标准的Matlab中。 These example data sets are valuable as test data when developing algorithms.
在开发算法时,这些示例数据集作为测试数据很有价值。
Where can one find a list of all such data sets included in Matlab? 在哪里可以找到Matlab中包含的所有这些数据集的列表?
You can enter demo
in matlab to get a list. 您可以在matlab中输入
demo
来获取列表。 The wind table is part of Example — Stream Line Plots of Vector Data
, etc. 风表是
Example — Stream Line Plots of Vector Data
一部分Example — Stream Line Plots of Vector Data
等。
For the tables on your computer, have a look at: 对于计算机上的表格,请查看:
C:\Program Files\MATLAB\R2007b\toolbox\matlab\demos
The example data is located in .mat
files in ../toolbox/matlab/demos
. 示例数据位于
../toolbox/matlab/demos
中的.mat
文件中。 The following data is available in MATLAB 2014a
: MATLAB 2014a
提供了以下数据:
% in matlab run:
> H=what('demos')
> display(H.mat)
You can also use your favorite Linux console: 您还可以使用自己喜欢的Linux控制台:
/usr/local/MATLAB/R2014a/toolbox/matlab/demos$ ls *.mat -1 | sed -e "s/.mat//g"
