When is a square lower triangular matrix invertible? When can a 3 \times 3 matrix be diagonalized? When is a square upper triangular matrix invertible? When is a matrix surjective? When does a matrix have a left
If we start with a value x close to one of these points, then (roughly speaking) it is highly possible that the algorithm will converge to that point. In general, after the choice of x , the algorithm generates a sequence of iterations (xk)k∈N with the aim of approaching the ...
