Signature de la méthode todense

def todense(self, order=None, out=None) 

Description

todense.__doc__

        Return a dense matrix representation of this matrix.

        Parameters
        ----------
        order : {'C', 'F'}, optional
            Whether to store multi-dimensional data in C (row-major)
            or Fortran (column-major) order in memory. The default
            is 'None', indicating the NumPy default of C-ordered.
            Cannot be specified in conjunction with the `out`
            argument.

        out : ndarray, 2-D, optional
            If specified, uses this array (or `numpy.matrix`) as the
            output buffer instead of allocating a new array to
            return. The provided array must have the same shape and
            dtype as the sparse matrix on which you are calling the
            method.

        Returns
        -------
        arr : numpy.matrix, 2-D
            A NumPy matrix object with the same shape and containing
            the same data represented by the sparse matrix, with the
            requested memory order. If `out` was passed and was an
            array (rather than a `numpy.matrix`), it will be filled
            with the appropriate values and returned wrapped in a
            `numpy.matrix` object that shares the same memory.
