NumPy is the abbreviation for Numerical Python. Instructions for installing NumPy can be found at instructions. NumPy has built-in functions to support array objects and a collection of routines, which can be utilized for logical operations and scientific computations. For example, it provides a package for Fourier Transformation. Once we have the library installed, engineering computation becomes easy. For example, we can compute Fourier transformations using one line of code:

signal_fft = fftpack.fft(signal)

Now, let's look at some of the operations that we can perform using NumPy.
