Creator of the dataset class
Syntax
dataset(data,symbols,vartypes,labels,variables)
data(datafile,variables,symbols,vartypes,labels)
Description
dataset(data,symbols,vartypes,labels,variables)
create a data object. data
are the data
(each piece of data is on a different line). labels
is
a column vector of the labels (optional) corresponding to each piece of data.
variables
[cell], are the names of the columns of the data.
symbols
[cell] are the symbolic correspondance for the symbolic data.
vartypes
is a cell array containing the type of the variable for each
column ('continuous','discrete','symbolic','class'). There can only be one 'class'
variable at a time. If vartypes is not specified, the types are deduced from the
data
and the symbol field
data(datafile,variables,symbols,vartypes,labels)
create a data object from a mat datafile. datafile
is the
name of the mat file where the data are saved. The file must contain a series of
variables referenced by variables
[cell]. Each of this variable must be a
column vector([double] or [cell]) of length equal to the number of data points.
