A matrix A has 3 rows and 4 columns: a11 a12 a13 a14 a21 a22 a23 a24 a31 a32 a33 a34 The 12 entries in the matrix are to be stored in row major form in locations 7609 to 7620 in a computer’s memory. This means that the entires in the first row (reading left to right) are stored first, then entries in the second row, and finally entries in the third row. Which location with a22 be stored...
