工程计算MATLAB code to calculate the reorthogonalized sine tapers

　　input: N = the length of the time series data to be tapered

　　 p = the number of tapers requested

　　 I = the gap structure a vector of length N

　　 I(t) = 1 if there is data at time t, t=1, ..., N

　　 I(t) = 0 if there is a gap at time t

　　output: X = N-by-p vector of the reorthogonalized sine taper-engineering MATLAB code to calculate the reorthog onalized sine tapers input : N = the length of the time series data to be tapere d p = the number of tapers I requested the gap str = ucture a vector of length N of I (t) = 1 if there is dat a at time t, t = 1, ..., I N (t) = 0 if there is a gap at time t output : X = N-by-p vector of the reorthogonalized sine t aper
