WebUsually with matrices you want to get 1s along the diagonal, so the usual method is to make the upper left most entry 1 by dividing that row by whatever that upper left entry is. So say the first row is 3 7 5 1. you would divide the whole row by 3 and it would become 1 7/3 5/3 1/3. From there you use the first row to make the first column have ... Web$\begingroup$ About "so the order of the permutation is even. Why are they asking this?" Look more closely at what they asked. They ask whether the permutation is even or odd, not whether its order is even or odd. A permutation is called even if it is the product of an even number of transpositions; it's called odd if it's the product f an odd number of … WebTo slice a multi-dimensional array, the dimension (i.e. axis) must be specified. As OP noted, arr[i:j][i:j] is exactly the same as arr[i:j] because arr[i:j] sliced along the first axis (rows) and has the same number of dimensions as arr (you can confirm by arr[i:j].ndim == arr.ndim); so the second slice is still slicing along the first dimension (which was already done by the … spectrum photographic ltd
