Array creation routines

From shape or value

empty(shape[, dtype, order, like])	Return a new array of given shape and type, without initializing entries.
empty_like(prototype[, dtype, order, subok, ...])	Return a new array with the same shape and type as a given array.
eye(N[, M, k, dtype, sparse, gpu, ...])	Return a 2-D array with ones on the diagonal and zeros elsewhere.
identity(n[, dtype, sparse, gpu, chunk_size])	Return the identity array.
ones(shape[, dtype, chunk_size, gpu, order])	Return a new array of given shape and type, filled with ones.
ones_like(a[, dtype, gpu, order])	Return an array of ones with the same shape and type as a given array.
zeros(shape[, dtype, order, like])	Return a new array of given shape and type, filled with zeros.
zeros_like(a[, dtype, gpu, order])	Return an array of zeros with the same shape and type as a given array.
full(shape, fill_value[, dtype, chunk_size, ...])	Return a new array of given shape and type, filled with fill_value.
full_like(a, fill_value[, dtype, gpu, order])	Return a full array with the same shape and type as a given array.

From existing data

array(x[, dtype, copy, order, ndmin, chunk_size])	array(object, dtype=None, *, copy=True, order='K', subok=False, ndmin=0,
asarray(a[, dtype, order, like])	Convert the input to an array.
ascontiguousarray(a[, dtype, like])	Return a contiguous array (ndim >= 1) in memory (C order).
copy(a[, order])	Return an array copy of the given object.

Numerical ranges

arange([start,] stop[, step,][, dtype, like])	Return evenly spaced values within a given interval.
linspace(start, stop[, num, endpoint, ...])	Return evenly spaced numbers over a specified interval.
meshgrid(*xi, **kwargs)	Return coordinate matrices from coordinate vectors.
mgrid	nd_grid instance which returns a dense multi-dimensional "meshgrid".
ogrid	nd_grid instance which returns an open multi-dimensional "meshgrid".

Building matrices

diag(v[, k, sparse, gpu, chunk_size])	Extract a diagonal or construct a diagonal array.
diagflat(v[, k, sparse, gpu, chunk_size])	Create a two-dimensional array with the flattened input as a diagonal.
tril(m[, k, gpu])	Lower triangle of an array.
triu(m[, k, gpu])	Upper triangle of an array.
