TD_CONVOLVE
Applies a series representing a digital filter to a time series by convolving the two series.
TD_CONVOLVE2
Performs a two-dimension convolution operation, convolving the first source with the second one.
TD_DFFT
Takes a time or space series as an input, and produces a result series containing the computed Fourier transform coefficients.
TD_DFFT2
Takes a matrix as an input, and returns a result matrix whose elements are the compute two-dimension Fourier coefficients for the input matrix.
TD_DFFTCONV
Converts an ART generated by TD_DFFT into a different result form.
TD_DFFT2CONV
Converts an ART generated by TD_DFFT2 into a different result form.
TD_GENSERIES4SINUSOIDS
Generates a result series containing a subset of the sinusoidal elements periodicities (sinusoids).
TD_IDFFT
Takes a frequency domain signal and converts it to a time domain signal.
TD_IDFFT2
Reconstructs the original input matrix from the matrix containing the computed two-dimension Fourier Coefficients previously generated using TD_DFFT2.
TD_LINESPEC
Identifies cycles that may be inherent in an input series.
TD_POWERSPEC
Converts a series from the time or spatial domain to the frequency domain in order to facilitate frequency domain analysis.
