- 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.
