Estimate the Holder exponent through an affine TFR.
H=holder(TFR,F,N1,N2,T)
affine time-frequency representation.
frequency values of the spectral analysis.
indice of the minimum frequency for the linear regression. (default : 1).
indice of the maximum frequency for the linear regression. (default : length(F)).
time vector. If T is omitted, the function returns the global estimate of the Holder exponent. Otherwise, it returns the local estimates H(T) at the instants specified in T.
output value (if T omitted) or vector (otherwise) containing the Holder estimate(s).
holder estimates the Holder exponent of a function through an affine time-frequency representation of it, and plots the frequency marginal and the regression line.
