COUNT_MATRIX_ELEMS

Obtains unique row elements from MxN matrix A and counts the number of occurrences.

COUNT_MATRIX_ELEMS - Obtains unique row elements from MxN matrix A and counts the number of occurrences. UN contains all matrix A distinct elements. C will have the same size as UN. UN(k) has C(k) occurrences in matrix A.

Example:

A = [1 2 3; 4 5 6; 1 2 3; 4 5 7; 1 2 1; 1 2 3; 4 5 6]
[UN, C] = count_matrix_elems(A)

A =

1 2 3
4 5 6
1 2 3
4 5 7
1 2 1
1 2 3
4 5 6

UN =
1 2 1
1 2 3
4 5 6
4 5 7

C =
1
3
2
