  # Python | Numpy np.ma.concatenate () method

Arrays | NumPy | Python Methods and Functions

Using the `np.ma.concatenate() ` method, we can concatenate two arrays using the ` np.ma.concatenate () ` method.

Syntax: ` np.ma.concatenate ([list1, list2]) `
Return: Return the array after concatenation.

Example # 1:
In this example we can see that with ` np.ma.concatenate () ` we can get the merged array using this method.

 ` # NumPy import ` ` import ` ` numpy as np ` ` import ` ` numpy.ma as ma `   ` gfg1 ` ` = ` ` np.array ([` ` 1 ` `, ` ` 2 ` `, ` ` 3 ` `]) ` ` gfg2 ` ` = ` ` np.array ([` ` 4 ` `, ` ` 5 ` `, ` ` 6 ` `]) `   ` # using the np.ma.concatenate () method ` ` gfg ` ` = ` ` ma.concatenate ([gfg1, gfg2]) `   ` print ` ` (gfg ) `

Output:

[1 2 3 4 5 6]

Example # 2:

 ` # NumPy import ` ` import ` ` numpy as np ` ` import ` ` numpy.ma as ma `   ` gfg1 ` ` = ` ` np.array ([` ` 11 ` `, ` ` 22 ` `, ` ` 33 ` `]) ` ` gfg2 ` ` = ` ` np.array ([` ` 41 ` `, ` ` 52 ` `, ` ` 63 ` `]) `   ` # using the np.ma.concatenate () method ` ` gfg ` ` = ` ` ma.concatenate ([ [gfg1], [gfg2]]) `   ` print ` ` (gfg) `
