A_CORRELATE Computes autocorrelation.
BLK_CON Convolves input signal with impulse-response sequence.
BUTTERWORTH Returns the absolute value of the low-pass Butterworth kernel.
C_CORRELATE Computes cross correlation.
CANNY Implements the Canny edge-detection algorithm.
CHEBYSHEV Returns the forward or reverse Chebyshev polynomial expansion.
CONVOL Convolves two vectors or arrays.
CONVOL_FFT Computes the convolution of an image using a product of Fourier transforms for speed.
CORRELATE Computes the linear Pearson correlation.
DIGITAL_FILTER Calculates coefficients of a non-recursive, digital filter.
FFT Returns the Fast Fourier Transform of an array.
FFT_POWERSPECTRUM Computes the Fourier power spectrum of an array.
GAUSS_SMOOTH Smoothes data using a Gaussian kernel. Also known as a Gaussian blur, it is typically used to reduce noise and detail in an image.
GAUSSIAN_FUNCTION Creates a Gaussian kernel used in convolution.
HANNING Creates Hanning and Hamming windows.
HILBERT Constructs a Hilbert transform.
INTERPOL Performs linear interpolation on vectors.
IR_FILTER Performs the infinite or finite impulse response filter on data.
LAMBERTW Returns the value W(z) of the Lambert W function, also known as the omega function or product logarithm function.
LEEFILT Performs the Lee filter algorithm on an image array.
M_CORRELATE Computes multiple correlation coefficient.
MEDIAN Returns median value of an array or applies a median filter.
P_CORRELATE Computes partial correlation coefficient.
R_CORRELATE Computes rank correlation.
SAVGOL Returns coefficients of Savitzky-Golay smoothing filter.
