This math image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}} .
It is recommended to name the SVG file “Fonctions pseudo-voigt.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
