    "abstract": "The explicit analytical expression of the Nonlinear Fourier Transform (NFT)\nof a finite set of data is provided. Then a simple recursion relation for the\nNFT is constructed as a function of the spectral parameter. These tools provide\na complete characterization of the nonlinear coherent structures (solitons,\nbreathers, ...) present in numerical or experimental data representing the\nsolution, at a given value of time, of a nonlinear evolution equation (e.g. of\nthe nonlinear Schroedinger family).",
