Assuming we have 3 matrices, A, B and C, all are of the same size 256x256. It is known that last 20% of columns of Matrix A is identical to first 20% of Matrix B and last 10% of Matrix B is identical to first 10% of Matrix C. So in these cases since we know the overlapping amount, I do not need to compare the 3 matrices, but i want to join them at the overlap.
Taking a smaller Matrix as an example here are the 3 Matrices
A = [1 2 3 4 ; 5 6 7 8; 9 10 11 12];
B = [3 4 13 14; 7 8 15 16; 11 12 17 18];
C = [14 19 20 21; 16 22 23 24; 18 25 26 27];
So I would like my output to be
D = [1 2 3 4 13 14 19 20 21
5 6 7 8 15 16 22 23 24
9 10 11 12 17 18 25 26 27
I hope this might explain it better. I am extremely new to matlab. I tried using matrix shift, but we have only circular shift available. Concatenation does not work because it just joins the 3 matrices. What would be the best way to overlay these 3 matrices together ?
Make proper use of matrix indexing and concatenation
For your example
D = [A B(:,3) C];
For a 256x256 Matrix and your concatenation conditions:
D = [A B(:, 0.2*256+1 : 0.9*256) C]
Since 256/10 is no integer you may adjust the index values
