Dec 10, 2019 at 3:14 comment added DisPxy @asterix314 Yes, but I should have added that number1, number2, and number3 change with j. which means that on {1,1} my number is 3, then j increments by one and now on {2,2} my number is 22.. etc.
Dec 10, 2019 at 3:01 comment added asterix314 Do you want a matrix with 3 bands? For size 5 try: SparseArray[{Band[{1, 1}] -> number1, Band[{2, 1}] -> number2, Band[{1, 2}] -> number2 }, {5, 5}] // MatrixForm
