---|---|
np.array() | |
np.arange(start, end, step) | |
np.linspace(start, end, count) | from start to end, equal margin |
np.copy() | |
np.hstack(tuple) | Stack arrays in sequence horizontally (column wise) |
np.vstack(tuple) | Stack arrays in sequence vertically (row wise) |
numpy.random.rand(d0,d1,d2,...,dN) | d is dimention,float values betweent 0 and 1 |
numpy.zeros(shape, dtype=float, order=‘C‘) | order = ‘C‘ is row-major, F is column-major storage in memory |
