new_swdft2d(a, x, n0, n1, type)

Arguments

• a: 4D complex-valued array of 2D SWDFT coefficients
• x: 2D real or complex valued signal
• n0: window size in row direction
• n1: window size in column direction
• type: algorithm to implement. defaults to "fftw", other option 'fft' for R's base FFT function. R's base fft function is used if
