get
(Not Recommended) Access dataset array properties
The dataset data type is not recommended. To work with heterogeneous data,
use the MATLAB®
table data type instead. See MATLAB
table documentation for more information.
Syntax
get(A)
s = get(A)
p = get(A,PropertyName)
p = get(A,{PropertyName1,PropertyName2,...})
Description
get(A) displays a list of property/value pairs
for the dataset array A.
s = get(A) returns the values in a scalar
structure s with field names given by the properties.
p = get(A,
returns the value of the property specified by
PropertyName)PropertyName.
p = get(A,{
allows multiple property names to be specified and returns their values in a cell
array.PropertyName1,PropertyName2,...})
Examples
Create a dataset array from Fisher's iris data and access the information.
load fisheriris
NumObs = size(meas,1);
NameObs = strcat({'Obs'},num2str((1:NumObs)','%-d'));
iris = dataset({nominal(species),'species'},...
{meas,'SL','SW','PL','PW'},...
'ObsNames',NameObs);
get(iris)
Description: ''
Units: {}
DimNames: {'Observations' 'Variables'}
UserData: []
ObsNames: {150x1 cell}
VarNames: {'species' 'SL' 'SW' 'PL' 'PW'}
ON = get(iris,'ObsNames');
ON(1:3)
ans =
'Obs1'
'Obs2'
'Obs3'
