numpy.matrix.flatten — NumPy v2.3.dev0 Manual (original) (raw)

method

matrix.flatten(order='C')[source]#

Return a flattened copy of the matrix.

All N elements of the matrix are placed into a single row.

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 m is Fortran contiguous in memory, row-major order otherwise. ‘K’ means to flatten m in the order the elements occur in memory. The default is ‘C’.

Returns:

ymatrix

A copy of the matrix, flattened to a (1, N) matrix where _N_is the number of elements in the original matrix.

ravel

Return a flattened array.

flat

A 1-D flat iterator over the matrix.

Examples

m = np.matrix([[1,2], [3,4]]) m.flatten() matrix([[1, 2, 3, 4]]) m.flatten('F') matrix([[1, 3, 2, 4]])
