Is There a Faster Way to Check the Diagonal of a Matrix for All 1s?

[Totam]

in matrix analysis, its easy to you can check if a matrix's diagonal is all 1s because u can only lo.ok at ex, 5x5 mattrix (1,1)(2,2)(3,3)(4,4)(5,5)
But what if u want to know about (1,2)(2,3)(3,4)(4,5) without checking as what i list ?
