Without using repmat, or for loop, or concatenation, create a function to duplicate a vector, v, a specified number of times, n. v can be numeric or character. n may be 0.

Examples

If

 v = 5;
 n = 3;

then return v1:

 v1 = [5 5 5] 

If a 2d matrix is supplied then the vector v will be the first column.

 V = magic(4);
 n = 4;

then v and v1 are returned as shown below.

 v = [16 5 9 4]'
 v1 = [16 16 16 16; 5 5 5 5; 9 9 9 9; 4 4 4 4] 

Hint: use indexing
