SyntaxC#
public class PeakFinderCWT
The PeakFinderCWT type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PeakFinderCWT | Initializes a new instance of the PeakFinderCWT class |
Methods| Name | Description | |
|---|---|---|
 | ContinuousWaveletTransformation | Executes a continuous wavelet transform over the data data. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Execute | Find peaks in a 1-D array with wavelet transformation. The general approach is to smooth `vector` by convolving it with wavelet(width) for each width in widths. Relative maxima which appear at enough length scales, and with sufficiently high SNR, are accepted. |
| FilterRidgeLines | Filter ridge lines according to prescribed criteria. Intended to be used for finding relative maxima. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetNoiseLevel | Gets the noise level along the x-axis. |
| GetRelativeExtrema(IReadOnlyListDouble, FuncDouble, Double, Boolean, Int32) | Gets a boolean array, in which local extrema in a spectrum are marked as true. |
| GetRelativeExtrema(IROMatrixDouble, FuncDouble, Double, Boolean, Int32, Int32) | Gets a boolean matrix of the same dimensions as the provided data matrix, in which the points at which a relative extrema is found, are set to true. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| IdentifyRidgeLines | Identifies the ridge lines in a continous wavelet transformation matrix |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| Ricker | Ricker wavelet function, also known as the "Mexican hat wavelet". |
| Ricker2ndDerivative | Normalized 2nd derivative of the Ricker wavelet function. |
| ScoreAtPercentile | |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
