# mx.nd.reshape.like¶

## Description¶

Reshape some or all dimensions of lhs to have the same shape as some or all dimensions of rhs.

Returns a view of the lhs array with a new shape without altering any data.

Example:

x = [1, 2, 3, 4, 5, 6]
y = [[0, -4], [3, 2], [2, 2]]
reshape_like(x, y) = [[1, 2], [3, 4], [5, 6]]

More precise control over how dimensions are inherited is achieved by specifying \
slices over the lhs and rhs array dimensions. Only the sliced lhs dimensions \
are reshaped to the rhs sliced dimensions, with the non-sliced lhs dimensions staying the same.


Example:

- lhs shape = (30,7), rhs shape = (15,2,4), lhs_begin=0, lhs_end=1, rhs_begin=0, rhs_end=2, output shape = (15,2,7)
- lhs shape = (3, 5), rhs shape = (1,15,4), lhs_begin=0, lhs_end=2, rhs_begin=1, rhs_end=2, output shape = (15)

Negative indices are supported, and None can be used for either lhs_end or rhs_end to indicate the end of the range.


Example:

- lhs shape = (30, 12), rhs shape = (4, 2, 2, 3), lhs_begin=-1, lhs_end=None, rhs_begin=1, rhs_end=None, output shape = (30, 2, 2, 3)


## Arguments¶

Argument

Description

lhs

NDArray-or-Symbol.

First input.

rhs

NDArray-or-Symbol.

Second input.

lhs.begin

int or None, optional, default=’None’.

Defaults to 0. The beginning index along which the lhs dimensions are to be reshaped. Supports negative indices.

lhs.end

int or None, optional, default=’None’.

Defaults to None. The ending index along which the lhs dimensions are to be used for reshaping. Supports negative indices.

rhs.begin

int or None, optional, default=’None’.

Defaults to 0. The beginning index along which the rhs dimensions are to be used for reshaping. Supports negative indices.

rhs.end

int or None, optional, default=’None’.

Defaults to None. The ending index along which the rhs dimensions are to be used for reshaping. Supports negative indices.

## Value¶

out The result mx.ndarray
