Hi, I would like to remove the i-th column and row from a two-dimensional array A. The remaining array should be kept and stored in B A = random.rand(n,n) This task is very easy if i is the first or last row/column. In that case one can use B = A[1:,1:] or B=A[:-1,:-1] But, what is the best way to get B if 0 < i < n-1 ? Nils
