find matching indexes
显示 更早的评论
I have two matrices:
A: x rows and 5 columns
B: x rows and 6 columns (the first column contains indexes)
The values of the matrix A are included in the matrix B. I would like to find the indexes of the matrix A (one row)

'(the first column contains indexes)' for matrix B or both??

Index_find = find(ismember(A,B));

Wow, apparently I guessed wrong about the question. Good work Karan.

I think you want something like
[x, ia, ib] = intersect(A, B(:, 2:end), 'rows');
B(1, ib)
