LTPDA_COHERE makes coherence estimates of the time-series objects %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: LTPDA_COHERE makes coherence estimates of the time-series objects in the input analysis objects. Coherences are computed using MATLAB's mscohere (>> help mscohere). CALL: b = ltpda_cohere(a1,a2,a3,...,pl) INPUTS: b - output analysis objects aN - input analysis objects (at least two) pl - input parameter list The function makes coherence estimates between all input AOs. Therefore, if the input argument list contains N analysis objects, the output, b, will contain NXN coherence estimates. If the last input argument is a parameter list (plist) it is used. The following parameters are recognised. PARAMETERS: Win - a specwin window object [default: Kaiser -200dB psll] Olap - segment percent overlap [default: taken from window function] Nfft - number of samples in each fft [default: half length of input data] Order - order of detrending. -1 - no detrending 0 - subtract mean [default] 1 - subtract linear fit N - subtract fit of polynomial, order N VERSION: $Id: ltpda_cohere.m,v 1.14 2008/08/10 20:16:49 hewitson Exp $ HISTORY: 07-02-2007 M Hewitson Creation %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
