Enter the elements of matrix
2
Element of Matrix at[0][0] is 2
4
Element of Matrix at[0][1] is 4
5
Element of Matrix at[1][0] is 5
6
Element of Matrix at[1][1] is 6
The value at predefined matrix are
Element of Matrix at[0][0] is 2
Element of Matrix at[0][1] is 4
Element of Matrix at[1][0] is 5
Element of Matrix at[1][1] is 6

Transpose of predefined matrix is
Element of Matrix at[0][0] is 2
Element of Matrix at[0][1] is 5
Element of Matrix at[1][0] is 4
Element of Matrix at[1][1] is 6
