Getting a contiguous array in NumPy

A contiguous array type is a specialized array that always stores its elements in a contiguous region of memory.

To get a contiguous array in numpy, we use numpy.ascontiguousarray() which returns a contiguous array (ndim >= 1) in memory (C order).

Syntax

numpy.ascontiguousarray(a, dtype=None, *, like=None)

Parameter(s)

• a: input array
• dtype: data type of returned array, can be str or dtype object.
• like: Reference object to allow the creation of arrays which are not NumPy arrays.

Let us understand with the help of an example,

Python code to get a contiguous array in NumPy

# Import numpy
import numpy as np

# Creating a numpy array
arr = np.ones((2, 3), order='F')

# Display original array
print("Original Array:\n",arr,"\n")

# Creating a contiguous array
res = np.ascontiguousarray(arr)

# Display result
print("append result:\n",res,"\n")

# Check if res is contiguous or not
print("Is res contiguous:\n",res.flags['C_CONTIGUOUS'])

Output
