Bases:
object
Raw interface to SigPy output /= width**ndim NUFFT.
- Parameters:
samples (np.ndarray) – the kspace sample locations in the Fourier domain, normalized between -0.5 and 0.5
oversamp (float default 1.25) – oversampling factor
width (int default 4) – interpolation kernel width (usually 3 to 7)
upsampfac (float, default 1.25) – Same as oversamp
eps (float, default 1e-4) – Other way of specifiying width.
