Referring to and Modifying the Matrix Elements:

To refer to matrix elements, the row and then the column indices are given in parentheses (always the row index initially and then the column). For illustration, this generates a matrix variable mat, and then refers to the value in the second row and third column of mat:

>> mat = [2:4; 3:5]

mat =

2 3 4

3 4 5

>> mat(2,3)

ans =

5
