ispeaky¶

Determines if spectra are considered peaky based on peakedness thresholds.

Syntax¶

function isPeaky = ispeaky(pkl, akl, pklThreshold, aklThreshold)

Description¶

ISPEAKY = ISPEAKY(PKL, AKL, PKLTHRESHOLD, AKLTHRESHOLD) determines if spectra are considered peaky based on peakedness thresholds. ISPEAKY is a logical array indicating which spectra meet both criteria (PKL >= PKLTHRESHOLD and AKL >= AKLTHRESHOLD).

Examples¶

% Using with peakedness function output
[pxx, f] = periodogram(signal, [], [], fs);
[pkl, akl] = peakedness(pxx, f, 0.3);
isPeaky = ispeaky(pkl, akl, 45, 85);

% Using with separate arrays
pkl = [30; 50; 70];
akl = [80; 90; 95];
isPeaky = ispeaky(pkl, akl, 45, 85);
% Result: [false; true; true] (only 2nd and 3rd spectra are peaky)
