InputTable Schema

Column Data Type Description
id_column Any Time series identifier.
time_column NUMERIC Time axis of data.
target_column NUMERIC [Column appears 1-16 times.] Signal value on which to perform FFT.

A 2-dimensional signal of length n is represented as a matrix of sqrt(n) rows and columns, stored in column-major order. (See FFT Example: 2D Signal.)

A 3-dimensional signal of length n is represented as a matrix of 2 matrixes of sqrt(n) rows and columns, stored in column-major order. (See FFT Example: 3D Signal.)
