nmrglue.process.proc_base.ha(data)

Hadamard Transform

Parameters

datandarray

Array of NMR data.

Returns

ndatandarray

Hadamard transform of NMR data.

Notes

This function is very slow. Implement a Fast Walsh-Hadamard Transform with sequency/Walsh ordering (FWHT_w) will result in much faster tranforms.
