Prefer .T over np.transpose() for matrix transposition

numpy_A_trans = numpy.transpose(numpy_A)

In the line:
numpy_A_trans = numpy.transpose(numpy_A)
it's recommended to use the shorthand .T instead:
numpy_A_trans = numpy_A.T
.T provides the same result as np.transpose() for 2D arrays, but with less overhead since it directly accesses the array's transpose attribute rather than calling a function. It also improves code readability and follows the idiomatic style in NumPy-based codebases.

This change improves both performance and clarity without affecting functionality.
