method
ndarray.flatten(order='C')
Return a copy of the array collapsed into one dimension.
Parameters:order{‘C’, ‘F’, ‘A’, ‘K’}, optional‘C’ means to flatten in row-major (C-style) order. ‘F’ means to flatten in column-major (Fortran- style) order. ‘A’ means to flatten in column-major order if a is Fortran contiguous in memory, row-major order otherwise. ‘K’ means to flatten a in the order the elements occur in memory. The default is ‘C’.
Returns:yndarrayA copy of the input array, flattened to one dimension.
