Python Coding with SciPy & MatPlotLib
computing. It is a collection of mathematical algorithms and convenience functions built on Numpy library. It provides the user with high-level commands and classes for manipulating and visualizing data. It provides many user-friendly and efficient numerical solutions such as routines for numerical integration and optimization.
SciPy is pronounced as Sigh Pie. It is an open-source Python library designed for technical and scientific computing.
SciPy provides advanced mathematical functions for optimization, integration, interpolation, linear algebra, statistics and signal processing.
I have used Jupyter Notebook as interpreter.
For all the examples Copy Paste version of all code examples are given, where you can use it in any of the interpreters you are using. You can change the attributes in these coding examples for trials and understanding.
In many of the SciPy code examples Numpy and Matplotlib are also used to get thorough understanding of SciPy Library.
Basics of MatPlotLib are explained in the last chapter
