Hey,
I have to write a LU-decomposition. My Code worked so far but (I want to become better:) ) I want to ask you, if I could write this LU-decomposition in a better way?
def LU(x):
L = np.eye((x.shape[0]))
n = x.shape[0]
for ii in range(n-1):
for ll in range(1+ii,n):
factor = float(x[ll,ii])/x[ii,ii]
L[ll,ii] = factor
for kk in range(0+ii,n):
x[ll,kk] = x[ll,kk] - faktor*x[ii,kk]
LU = np.dot(L,x)
Thanks
