I have a matrix, A which have a 9 row and 9 column. I need to make a subset from it.
The prospective subset we need : S1= [ 1 4 7] ; S2 =[2 5 8]; S3= [3 6 9]
Here S1 is telling that I need matrix that will take the element of 1st, 4th, 7th row of the matrix A and by doing vertical concatenation the matrix is perfectly formed.
I did like following which works perfect but I am wondering if my matrix is very large then is there any alternating way to that ? something like usiing some loops?
% Creating Matrix Subset
A=randi(9,9);
S1_a= A(1,:);
S1_b= A(4,:);
S1_c= A(7,:);
S1 = [S1_a; S1_b; S1_c] ; % Vertically concatenate
