function [mappedA mapping] = compute_mapping(A type no_dims varargin)
%COMPUTE_MAPPING Performs dimensionality reduction on a dataset A
%
% mappedA = compute_mapping(A type)
% mappedA = compute_mapping(A type no_dims)
%
% Performs a technique for dimensionality reduction on the data specified
% in A reducing data with a lower dimensionality in mappedA.
% The data on which dimensionality reduction is performed is given in A
% (rows correspond to observations columns to dimensions). A may also be a
% (labeled or unlabeled) PRTools dataset.
% The type of dimensionality reduction used is specified by type. Possible
% values are ‘PCA‘ ‘SPCA‘ ‘LDA‘ ‘ICA‘ ‘MDS‘ ‘Isomap‘ ‘LandmarkIsomap‘
% ‘LLE‘ ‘Laplacian‘ ‘HessianLLE‘ ‘LTSA‘ ‘DiffusionMaps‘ ‘KernelPCA‘
% ‘GDA‘ ‘SNE‘
