Find the number of rows and columns of non-zero number from certain row.

Given a matrix named Matr below;

Matr =
     0     0
     0     0
     1     0
     0     0
     2     0
     0     1
     1     1

How can I find the number of column and row form beginning of row to only row 6?

The result should be

[3 1
 5 1
 6 2]

You can do something like this

[r, c] = find(Matr(1:6,:));
res = [r c]
%res =
%
%     3     1
%     5     1
%     6     2
