If I understand the sequence, you want the odd columns from the odd
rows and the even columns from the even rows to "a" and the
remainder go to "b". Once you have a transposed matrix, the recipe
looks straightforward.

dear Researcher
Sorry that I know this is not the right email-list and this is a basic help
but I am doing a remotesensing filter and I am honest, I have no idea how I
can do this.
I have a sequance form 1 to 16
> seq(1:16)
[1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
and I wish to select this combination in a vector
a <- c(1,3,6,8,9,11,14,16)
b <- c(2,4,5,7,10,12,13,15)
following the below example
t(matrix(data = seq(1:16), nrow = 4, ncol = 4))
[,1] [,2] [,3] [,4]
[1,] 1 2 3 4
[2,] 5 6 7 8
[3,] 9 10 11 12
[4,] 13 14 15 16
