http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/wavelet/wrcoef2.html Webupcoef is a one-dimensional wavelet analysis function. Y = upcoef (O,X, ' wname ' ,N) computes the N -step reconstructed coefficients of vector X. ' wname ' is a string containing the wavelet name. See wfilters for more information. N must be a strictly positive integer. If O = 'a', approximation coefficients are reconstructed.
