stageraw2bin¶

stageraw2bin(stages_raw, stagetime_raw, bin, epoch, domaindivide)

STAGERAW2BIN Convert (stage_time, stage_val) hypnogram into a binned stage train and one-hot stage matrix

Usage:: [stage, stagetrain] = stageraw2bin(stages_raw, stagetime_raw, bin, epoch, domaindivide)
Inputs:: stages_raw : 1xS double - raw stage values (1=N3, 2=N2, 3=N1, 4=REM, 5=Wake) – required stagetime_raw : 1xS double - raw stage onset times (s) – required bin : double - target bin size (s) – required epoch : double - stage epoch length (s) – required domaindivide : 1x(B+1) double - bin edges – required
Outputs:: stage : Bx5 double - one-hot stage matrix in [N1 N2 N3 REM Wake] column order stagetrain : Bx1 double - per-bin stage code

Notes

When bin <= epoch, samples are expanded by the epoch/bin ratio; otherwise stages are aggregated per-bin via histcounts.
