Methods
 NameDescription
Public methodStatic memberCreateInterpolationDataByContinuation Creates interpolation data for the envelope by continuing the extrema trend at the boundaries.
Public methodStatic memberCreateInterpolationDataByMirroring Creates interpolation data for the envelope by mirroring the extrema at the boundaries.
Public methodEqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
Public methodExtractIntrinsicModeFunctionComponent Extracts an intrinsic mode function component (IMF) from the signal (x, y).
Public methodExtractIntrinsicModeFunctionComponents Extracts the intrinsic mode function components (IMFCs) of a signal by empirical mode decomposition.
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
Public methodGetHashCodeServes as the default hash function.
(Inherited from Object)
Public methodGetTypeGets the Type of the current instance.
(Inherited from Object)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Public methodSubtractMeanEnvelope Subtracts the mean envelope from the signal signal.
Public methodStatic memberSubtractMeanEnvelope_1_1 Subtracts the mean envelope from the signal in the special case where there is exactly one minimum and one maximum.
Public methodToStringReturns a string that represents the current object.
