It set the first 2 elements and not the 12'th!!
You are assigning -1 to column 0 thirteen times and assinging -1 to column 1 once. For now, until boolean indexing works with matrices, I would just use brute force: A[row,where(all_dates.A == 10)[0]] Or you can do all rows at once with A[all_dates== 10] where all_dates is the same size as A.
