Shaping

Stacking

concatenate(arrays[, axis, out])	Join a sequence of arrays along an existing axis.
dstack(tup)	Stack arrays in sequence depth wise (along third axis).
hstack(tup)	Stack arrays in sequence horizontally (column wise).
stack(arrays[, axis, out])	Join a sequence of arrays along a new axis.
vstack(tup)	Stack arrays in sequence vertically (row wise).

Splitting

array_split(ary, indices_or_sections[, axis])	Split an array into multiple sub-arrays.
dsplit(ary, indices_or_sections)	Split array into multiple sub-arrays along the 3rd axis (depth).
hsplit(ary, indices_or_sections)	Split an array into multiple sub-arrays horizontally (column-wise).
split(ary, indices_or_sections[, axis])	Split an array into multiple sub-arrays.
vsplit(ary, indices_or_sections)	Split an array into multiple sub-arrays vertically (row-wise).

Shape manipulation

atleast_1d(*arys)	Convert inputs to arrays with at least one dimension.
atleast_2d(*arys)	View inputs as arrays with at least two dimensions.
atleast_3d(*arys)	View inputs as arrays with at least three dimensions.
broadcast_arrays(*args, **kwargs)	Broadcast any number of arrays against each other.
expand_dims(a, axis)	Expand the shape of an array.
moveaxis(a, source, destination)	Move axes of an array to new positions.
repeat(a, repeats[, axis])	Repeat elements of an array.
reshape(a, newshape[, order])	Give a new shape to an array without changing its data.
tile(A, reps)	Construct an array by repeating A the number of times given by reps.
transpose(a[, axes])	Permute the dimensions of an array.
