spectral_estimation

• corr — correlation, covariance
• cspect — two sided cross-spectral estimate between 2 discrete time signals using the correlation method
• czt — chirp z-transform algorithm
• intdec — Changes sampling rate of a signal
• mese — maximum entropy spectral estimation
• pspect — two sided cross-spectral estimate between 2 discrete time signals using the Welch's average periodogram method.
