toimage — transforms a spectrum made of 1D functions in an 2D image
[im,tt,ff] = toimage(A,f) [im,tt,ff] = toimage(A,f,t) [im,tt,ff] = toimage(A,f,splx) [im,tt,ff] = toimage(A,f,splx,sply) [im,tt,ff] = toimage(A,f,t,splx) [im,tt,ff] = toimage(A,f,t,splx,sply)
amplitudes of modes (1 mode per row of A)
instantaneous frequencies
time instants
number of columns of the output im (time resolution).If different from length(t), works only for uniform sampling.
number of rows of the output im (frequency resolution).
2D image of the spectrum
time instants in the image
centers of the frequency bins
toimage transforms a spectrum made of 1D functions (e.g., output of "hhspectrum") in an 2D image
