Using NumPy for array and matrix math in Python Many mathematical operations, especially in machine learning or data science, involve working with matrixes, or lists of numbers.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The data collection matrix makes possible the integration of functional area data from numerous assessment sources and presentation of the information in a unified composite report. The matrix model ...

Real-world compositional data sets are often complex owing to high-dimensionality, heavy tails, and the possible existence of outliers. We consider a general class of elliptical distributions to model ...
