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
◆ fft()
| 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 199 of file complexdata.h.
◆ modulate_offset()
| 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.
Definition at line 297 of file complexdata.h.

Assignment operator for expression templates
Definition at line 134 of file complexdata.h.
◆ operator=() [2/4]

Assignment operator
Definition at line 104 of file complexdata.h.
◆ operator=() [4/4]
|
inline |
Fills all elements with 'val'
Definition at line 116 of file complexdata.h.
◆ partial_fft()
| 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 226 of file complexdata.h.
◆ phasemap()
| Data< float, N_rank > ComplexData< N_rank >::phasemap |
Returns the phase of the complex array, whereby the phase is unwrapped in the last dimension
Definition at line 338 of file complexdata.h.
◆ shift_subpixel()
| 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.
