% prd=dftoperiod(d,b,t) - estimate period from difference function % % prd: row matrix of period estimates % % d: column vector or matrix of difference functions % b: bounds matrix ([lo, hi]) % t: threshold % % Difference functions are supposed to be cumulative-mean-normalized. % For each column of d, search for the first minimum between lo and hi that % falls below threshold. The index of this minimum (re 0) is the period estimate. % % Mex function.
