MATLAB: Concatenating even and odd rows

columnsevenoddrows

I have a matrix. and I am trying to place odd rows on the left side and even rows data on the right sid

which means row 2 data will be placed in 17 to 32 columns of row 1

row 3 data will be placed in row 2 (1 to 16 columns ) and row 4 data will be placed in 17 to 32 columns of row 2.

row 5 data will be placed in row 3 (1 to 16 columns) and row 6 data will be placed in 17 to 32 columns of row 3

A=rand(10,16);
B=[A(1:2:end,:),A(2:2:end,:)]

Paulo answered the question as you phrased it, but if you know the exact number of results you are producing (or if the maximum number of results is "reasonably close" to the likely number of results), then you are better off pre-allocating memory for the results:

a = zeros(10,1);
for b = 1:10
  a(b) = 3*b+5;  %for example
end

When you get to thousands of elements, pre-allocating can be much much faster.

MATLAB: Splitting a matrix by even and odd numbers

use rem to determine which list of numbers is even or odd

X = [1 3 4 2 5 4 2] % hint X is the first column of your matrix
iseven = rem(X,2)==0

use this logical vector to select the whole row of M
