A2 will aways be larger than T1. Iterate Through a Matrix Using Linear Indexing in MATLAB In a matrix, there are two kinds of indexing; one is the row and column indexing in which we have to give the row and column number to access an element present in the matrix, second is the linear indexing in which we can access an element using only its linear index.
