Replicate from duplicate in MATLAB

Replicate each element of a row vector (with NaN) a constant number of times.

Examples n=2, A=[1 2 3] -> [1 1 2 2 3 3]

n=0, A=[2 1] -> []

Prerequisite:

Code:

x=input('Enter the array:');

n=input('Enter the number:');

Y=[];

for i=1:length(x)

    m=x(i);

    for i=1:n

        Y=[Y m];

    end

end

Explanation:

Output:

JAVA CODE:

import java.util.Scanner;

class Ghin

{

public static void main(String args[])

{

Scanner obj=new Scanner(System.in);

System.out.println("Enter the array length:");

int l=obj.nextInt();

int a[]=new int[l];

for(int i=0;i<l;i++)

{

System.out.println("Enter the number:");

a[i]=obj.nextInt();

}

System.out.println("Enter the number you want to replicate:");

int r=obj.nextInt();

int m=0;

int op=0;

int u[]=new int[l*r];

for(int i=0;i<l;i++)

{

m=a[i];

for(int p=0;p<r;p++)

{

u[op]=m;

op=op+1;

}

}

System.out.println("The replicated matrix is:");

for(int i=0;i<l*r;i++)

{

System.out.print(u[i]+" ");

}

}

}

OUTPUT:

Example 1:

If we want to replicate 0 times , no output is shown :

Example 2:
