[BC] Error when calculating ifft of DataFreq containing only one frequency #86
Description
As shown in test_fft1d_non_uniform() of Tests\Validation\test_fft.py, the ifft of a DataFreq with a single frequency crashes when requesting the DataTime on an input time arrays ("time=axis_data").
A possible workaround is to add another value in frequency axis and zero padding the DataFreq consequently.
