Summary
[edit]DescriptionSinc function (normalized).svg |
English: Graph of the normalized sinc function sin(πx)/(πx).
The original was generated by gnuplot, while the more recent one was generated with matplotlib. File size was reduced by efficient coding of the axis drawing and labeling and by a reworking of the graph's path. The resulting path is smoother even though fewer points are used in its determination.This 10.81 was created with a text editor. Please do not replace the simplified code of this file with a version created with Inkscape or any other vector graphics editor Omegatron's instructions: This plot was created with Gnuplot by v. |
