How I can convert this matlab code to python? [closed]

by

I would be careful about the indexing of u and y when using nbefore and nafter so that I don’t get index out of bounds error.

Here is a Pythonic way –

ynew = [dt * u[i] + y[i] for i in xrange(1,n+1)]
unew = [dt * (k / m) * (y[i+1] + y[i-1]) for i in xrange(1,n+1)]
