Take the inverse 2D FFT of input data described functionally, returning the inverse transform also as a function
Take the inverse 2D FFT of "matrix".
Return true if "value" is an exact power of 2.
Return true if "value" is an exact power of 2.
Take the logarithm of "value" base 2.
Take the logarithm of "value" base 2.
Take the 2D FFT of input data described functionally, returning the transform also as a function
Take the 2D FFT of "matrix".
Object which performs a 2D FFT (and its inverse) on 2-dimensional, complex data.
The number of rows and columns in the data must each be a power of 2.
