Problem in matching a subset of columns of two matrices

1 次查看(过去 30 天)
I have the following matrices:
*********************
Training data set: T
*********************
1 2 0
1 3 1
1 4 1
0 2 0
0 3 0
0 4 1
0 3 1
0 4 0
*********************
Generated Rules: R
*********************
-1 2 0
1 3 1
1 4 1
0 3 0
0 4 0
0 3 1
0 4 1
Problem:
I want to compare the first two columns of matrix R with each row of the matrix T and if matched write all the matching rows of T into a separate matrix. A help is needed.
Thanks in advance.

Thanks Walter,
Thanks for the answer but i want to take one row of T each time and compare with all rows of R for match, if row(s) match then write all those into a new matrix. I want to repeat the same process for all rows of T and as a result, I will get more matrices (not one) for the matched rows.
Needs your nice comments.
Thanks Rahman Ali

NewT = T(ismember( T(:,[1 2]), R(:,[1 2]), 'rows'), :);
