Multitaper power spectral density estimate

`[pxx,w] = pmtm(___)``[pxx,f] = pmtm(___,fs)`example

`[pxx,w] = pmtm(x,nw,w)``[pxx,f] = pmtm(x,nw,f,fs)`

`[___] = pmtm(___,method)`example

`[___] = pmtm(x,e,v)`example`[___] = pmtm(x,dpss_params)`

`pmtm(___)`

` pxx = pmtm(x)` returns
Thomson's multitaper power spectral density (PSD) estimate
of the input signal,

`[ pxx,w]
= pmtm(___)` returns the normalized frequency
vector,

`[ pxx,f]
= pmtm(___,fs)` returns
a frequency vector,

`[ pxx,w]
= pmtm(x,nw,w)` returns
the two-sided multitaper PSD estimates at the normalized frequencies
specified in the vector,

`[ pxx,f]
= pmtm(x,nw,f,fs)` returns
the two-sided multitaper PSD estimates at the frequencies specified
in the vector,

`[___] = pmtm( x,e,v)` uses
the tapers in the N-by-K matrix

`[___] = pmtm( x,dpss_params)` uses
the cell array,

x = randn(1000,1); pxx = pmtm(x,{2.5,3});

`[___] = pmtm(___,'DropLastTaper', dropflag)` specifies
whether

`[___] = pmtm(___, freqrange)` returns
the multitaper PSD estimate over the frequency range specified by

: `'onesided'`, `'twosided'`,
or `'centered'`.

`[ pxx,f,pxxc]
= pmtm(___,'ConfidenceLevel',probability)` returns
