Ask for creating new matrix from Odd-Indexed and Even-Indexed Elements

3 vues (au cours des 30 derniers jours)
Hi,
I have two existing matrix with element of 371x2 and I would like to create the new one with 743x2 by putting the odd row with first matrix and even row with the second matrix following sample below;
Matrix A
1 2
5 6
9 10
. .
. .
Matrix B
3 4
7 8
11 12
. .
. .
New matrix C
1 2
3 4
5 6
7 8
9 10
11 12
. .
. .
I try the code following below but it didn't work. Could you please correct my code.
C = zeros(743,2);
[C(1:2:end,:),C(2:2:end,:)] = (A,B);
Thanks

Hi Phat,
you're close
C = zeros(742,2);
C(1:2:end,:) = A;
C(2:2:end,:) = B;

Hi David,
Many thanks to this. Once again, if I would like to add one more column with an array of 371x1 to be in the 3rd coloumn of matrix C. How can I code it?
Thanks

right now C is 742x2 and your new matrix D is 371x1. You can't make a third column of C with it because it doesn't have enough rows. Would you put zeros for the rest of the rows?
