Let us take a rotation curve of a spiral galaxy. This program makes the calculus of the inverse of the matrix of forces in a maximal disk, view as a set of stars (or points) with usual symmetry. After, it realizes the calculus of masses and of the surface density of the disk. No halo of dark matter is need. The mass of the twin galaxies, Milky Way and Andromeda, for the same radius from 30 to 38 kpc are similar and in the interval [2.3 10^11, 3.5 10^11] times the solar mass.

Mots clés: rotation curves; Milky Way; Andromeda; spiral galaxy; "maple" logiciel; no dark matter.
