Scientific Computing Using SAGE [ID:245]

a series of video-tutorials by unpingco

SAGE is an open-source project to integrate the best open-source scientific packages under an interactive environment. SAGE aims to provide an open-source alternative to commercial packages such as MATLAB and Mathematica. This tutorial series covers how to use SAGE for a variety of problems.

Video Tutorials

1. Scientific Computing Using SAGE: Introduction

In this overview video for SAGE, we introduce the basics of the notebook browser-based interface and demonstrate the basics of using the interactive environment. SAGE uses Python for scripting, Python libraries that are referenced include NumPy and matplotlib. Here Python is shown along with 2D plotting and SAGE is run inside Firefox.

2. Two-Dimensional Plots in SAGE

In this part, we discuss two-dimensional plotting in SAGE using symbolic expressions and data lists. We illustrate the usefulness of certain Firefox extensions from the browser-based SAGE notebook interface.

3. Three-Dimensional Plots in SAGE

In this segment, we discuss plotting three-dimensional mathematical functions in SAGE, how to overlay a corresponding colormap, how to draw primitive solids, as well as how three-dimensional graphics are handles in SAGE's browser interface.

4. Using @interact to Add GUI Controls to Computations

In this segment, we explore SAGE's powerful @interact feature that allows embedding of certain GUI controls into your SAGE notebook computations.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.
