Detailed Description
template<int N_rank>
class ComplexData< N_rank >
This template class holds multidimensional complex data, most suitable for NMR signal. In addition to functionality provided by the Data Array class, it offers advanced numerical routines (FFT) and block-wise processing of large data files.

Member Function Documentation
| void ComplexData< N_rank >::fft | ( | bool | forward = true, |
|
| bool | cyclic_shift = true | |||
| ) |
Performs an in-place FFT with the following properties:
- forward: Whether to do a forward (true) or backward (false) FFT
- cyclic_shift: Whether to shift data cyclically so that zero frequency is in the middle of the array after FFT
Definition at line 178 of file complexdata.h.
| void ComplexData< N_rank >::modulate_offset | ( | const TinyVector< float, N_rank > & | rel_offset | ) |
Modulate a phase gradient onto the array so that after FFT, the data will be shifted in each dimension by 'rel_offset' which is given as a fraction relative to the full size, i.e. a value of 0.5 shifts the array by half its size.

| void ComplexData< N_rank >::partial_fft | ( | const TinyVector< bool, N_rank > & | do_fft, | |
| bool | forward = true, |
|||
| bool | cyclic_shift = true | |||
| ) |
Performs an in-place FFT over a partial number of dimensions with the following properties:
- do_fft: A vector where the index should be set to 'true' if the FFT should be performed for the corresponding dimension
- forward: Whether to do a forward (true) or backward (false) FFT
- cyclic_shift: Whether to shift data cyclically so that zero frequency is in the middle of the array after FFT
Definition at line 205 of file complexdata.h.
| Data< float, N_rank > ComplexData< N_rank >::phasemap | ( | ) | const |
Returns the phase of the complex array, whereby the phase is unwrapped in the last dimension
Definition at line 315 of file complexdata.h.
| void ComplexData< N_rank >::shift_subpixel | ( | const TinyVector< float, N_rank > & | shiftvec | ) |
Shift the data by the number of pixels given in 'shiftvec' for each dimension using the FFT, i.e. this is possible even with fractions.
