Repetition of rows of a matrix maintaining the number of columns

Hi all.

My case is very similar to this one: http://www.mathworks.es/matlabcentral/answers/7258-pasting-row-elements-as-matrix

I also want to create a new matrix from a previous one (A) such all the elements in the first row are copied with N replications and the same should be done for the next row till I reach last row.

The order of new matrix is also N * [rows(A)*cols(A)]; but in my case its number of rows has to be N*rows(A) and the number of columns has to be the same as the previous (A) matrix.

For example, imagine my A matrix is A=[ 1 2

                           3 4
                           5 6]
If I replicate N=2 all the rows, my new A_ matrix should be A_=[1 2
                                                                1 2 
                                                                3 4
                                                                3 4
                                                                5 6
                                                                5 6]
 Can you help me, please?
Thanks and regards

+1 Well written question with sample data, operation, result and proof you searched the records (a rarity)!

Answer 1

[Paulo Silva]

A=[ 1 2
    3 4
    5 6]
N=1;                 %number of repeats
kron(A,ones(N+1,1))

+1`But I'd recommend for readability purpose keeping N to be the number of repeats as a multiplicative number, i.e. 1 repeat = what you have, two repeats = Ivan's example etc.
