General Rules

• Commit messages must have a subject line and may have body copy. These must be separated by a blank line.
• The subject line must not exceed 50 characters
• The subject line should be capitalized and must not end in a period
• The subject line must be written in imperative mood (Fix, not Fixed / Fixes etc.)
• The body copy must be wrapped at 72 columns
• The body copy must only contain explanations as to what and why, never how. The latter belongs in documentation and implementation.

Discovering the Fourier Transform: A Tutorial on Circulant Matrices, Circular Convolution, and the DFT

• Paper source
• video

Summary

• Discrete Fourier Transform (DFT) arises naturally out of analysis of circulant matrices
• DFT can be derived as the change of basis that simultaneously diagonalizes all circulant matrices
