Bbuild a program that performs a horizontal concatenation of two n*m matrices: (merges the matrices)

i.e: n =3, m = 5

Matrix a :

1 2 3 4 5

6 7 8 9 10

11 12 13 14 15

Matrix b :

16 17 18 19 20

6 7 8 9 10

11 12 13 14 15

Horizontal Concatenation Matrix:

1 2 3 4 5 16 17 18 19 20

6 7 8 9 10 6 7 8 9 10

11 12 13 14 15 11 12 13 14 15

The program should contain two functions :

-concatenate()that takes 2 vectors as parameters and return an array containing the two vectors

Example: for m = 5

Vector a: 1 2 3 4 5

Vector b: 6 7 8 9 10

Concatenated array: 1 2 3 4 5 6 7 8 9 10

-horizontalConcatenation()that takes two matrices as parameters and returns a matrix representing their concatenation. This function should use the concatenate () function
