代码片段和文件信息
function res = KLExpansion(dataMtopKN)
% USAGE:
%
% res = KLExpansion(dataMtopKN)
%
% Input Arguments:
% data each column contains the measurements for one variable
% each row contains the variables for one measurement interval
% M temporal correlation range (0 < M < 10)
% topK spatial correlation range (1 < topK < #cols data)
% N the first N intervals are used for training (20 < N < #rows data)
%
% Output:
% res vector of residual values has same number of rows as data
%
% Examples & Remarks:
% KLExpansion(data13100)
% Computes a PCA model using the 3 largest eigenvectors on
% the first 100 intervals of data uses the model to predict
% timeseries and returns residual
% KLExpansion(data43100)
% Computes a KLE model using the 3 largest eigenvectors and a
% temporal correlation range of 4 on the first 100 intervals
% of data uses the model to predict timeseries and returns
% residual
