How to find a column with a specific set of numbers

Hello so I have a matrix like this:

0 5 5 0 0 6 11 11 6 6

0 0 5 5 0 0 0 5 5 0

0 0 0 0 0 0 0 0 0 0

How can I find which columns has the [6;0;0] which in this case is columns 6 and 10?

Thank you

Use ismember() with 'rows' option.

% m is your matrix 
colIdx = ismember(m.', [6 0 0], 'rows')';  % note the transpose of m
colNum = find(colIdx);  % column numbers that match 6;0;0

Columns = find(all(matrix==[6;0;0]))
