Matrices et Python
August 24th, 2007 by Melaneum
Une bien jolie matrice sous la main, et on aimerait bien trouver son inverse:
from numpy import *
from numpy.linalg import *
a=array([[ 2.34635649, -1.36700425, 2.62820772, -1.93379678],
[-0.1883465 , 0.24001098, -0.16084023, 0.06769621],
[-0.45821679, 0.66405128, -0.93736998, 0.47861882],
[-1.23335039, 0.54581151, -1.04212985, 1.05308756]])
inva=inv(a)
Et pour vérifier tout ca: dot(a,inva) (on a bien une matrice identité).
