MATLAB Merging Arrays -

i unable figure out how merge 2 arrays. data arrays , b.

a = [ 0 0; 0 0; 2 2; 2 2;]  b = [ 1 1; 1 1; 3 3; 3 3; 4 4; 4 4; 5 5; 5 5;] 

and need final array "c" after merging:

c = [ 0 0; 0 0; 1 1; 1 1; 2 2; 2 2; 3 3; 3 3; 4 4; 4 4; 5 5; 5 5;] 

i've tried using different ways reshaping each array , trying use double loop haven't got work yet.

in actual data inserting 9 rows of array b following 3 rows of array , repeated 100 times. so, there 12 new merged rows (3 rows array , 9 rows array b) repeated 100 times final row number == 1200. array actual data has 300 rows , actual array b data has 900 rows

thanks,

here's solution using reshape:

a = [ 6 6; 3 3; 5 5; 4 4;] b = [ 0 0; 21 21; 17 17; 33 33; 29 29; 82 82;]  a_count = 2; b_count = 3;  w = size(a,2); %// width = number of columns  ar = reshape(a,a_count,w,[]); br = reshape(b,b_count,w,[]);  cr = [ar;br]; c = reshape(cr,[],w) 

the [] in reshape means "how ever many need total number of elements". if have 12 elements in b , do:

br = reshape(b,3,2,[]); 

we're reshaping b 3x2xp 3-dimensional matrix. since total number of elements 12, p = 2 because 12 = 3x2x2.

output:

a =     6   6    3   3    5   5    4   4  b =      0    0    21   21    17   17    33   33    29   29    82   82  c =      6    6     3    3     0    0    21   21    17   17     5    5     4    4    33   33    29   29    82   82
