So if you want to create or do calculation on matrix using numpy then you have to numpy.

Numpy use cases

In image preprocessing numpy is widely used. We know that images are noting but matrix. To work with image matrix, you have to use numpy.
For machine learning, deep learning, you will need numpy. For signal processing, scientific computing, data analysis and manipulation you will need numpy. The main thing is, where you need to work with array or matrix, there you will need numpy and there is a huge area where you will work with matrix. So learn numpy.
