You are given a matrix of m rows and n columns. Write a function that calculates the transpose of the given matrix.
The transpose of a matrix is obtained by changing rows to columns and columns to rows. For example, the transpose of the matrix
[[1, 2, 3],
[4, 5, 6],
[7, 8, 9]]
is
[[1, 4, 7],
[2, 5, 8],
