labelmean¶
Synopsis¶
Takes the mean of columns with the same label (source code).
Usage¶
label_data = labelmean(data,label,varargin);
- data: an n-by-m data matrix.
- label: a 1-by-m label vector containing natural numbers.
- label_data: n-by-max(label) matrix containing the mean column of each label.
- varargin: See below.
Description¶
A fast way of computing the mean for each label. Accepts the following additional arguments in varargin:
- sortByLabelVector: Sorts the columns of
label_data
by the order of appearance in thelabel
vector, rather than ascending order. - ignoreWarning: Does not display order of column sorting or warnings due to 0s in the label vector.
