watex.utils.reshape

watex.utils.reshape(arr, axis=None)

Detect the array shape and reshape it accordingly, back to the given axis.

Parameters

• array – array_like with number of dimension equals to 1 or 2

• axis – axis to reshape back array. If ‘axis’ is None and the number of dimension is greater than 1, it reshapes back array to array-like

Returns

New reshaped array

Example

>>> import numpy as np
>>> from watex.utils.funcutils import reshape
>>> array = np.random.randn(50 )
>>> array.shape
... (50,)
>>> ar1 = reshape(array, 1)
>>> ar1.shape
... (1, 50)
>>> ar2 =reshape(ar1 , 0)
>>> ar2.shape
... (50, 1)
>>> ar3 = reshape(ar2, axis = None)
>>> ar3.shape # goes back to the original array
>>> ar3.shape
... (50,)
