My question is to check each row for the same numbers (in this case 1 or 0, we leave the 0s unchanged in the matrix), and replace any 1 in the row with 0 except the last value of 1. Another similar question would be to remover the first/second (sometimes even third) number in the row leaving the last ... WebFor a matrix A, we write a ijto denote the entry in the ithrow and jthcolumn of A (for each i = 1,2,3 and j = 1,2,3). We write either A = (a ij) or [A] ij= a ij– these equations are equivalent – to indicate this. (Sometimes the upper-case letter is used instead, in which case the matrix A would have entries A ij.)
