Hi,

I want to convert these function in Python to C++. Everybody can help?

Python

def rnd(a):
   h, w = a.shape[:2]
   T = np.zeros((2, 3))
   coef = 0.2
   ang = (np.random.rand()-0.5)*coef
   c, s = np.cos(ang), np.sin(ang)
   T[:2, :2] = [[c,-s], [s, c]]
   T[:2, :2] += (np.random.rand(2, 2) - 0.5)*coef
   c = (w/2, h/2)
   T[:,2] = c - np.dot(T[:2, :2], c)
return T

def div(A, B):
   Ar, Ai = A[...,0], A[...,1]
   Br, Bi = B[...,0], B[...,1]
   C = (Ar+1j*Ai)/(Br+1j*Bi)
   C = np.dstack([np.real(C), np.imag(C)]).copy()
return C

Thank in advance,

Well, if you are waiting for permission, consider it given.

Otherwise...it doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.

But be aware: you get what you pay for. Pay peanuts, get monkeys.

I think i need your help for a simple problem. You are experts, aren't you?

barneyman 26-Oct-14 23:38pm

how far have you got, and what are you stuck on?

OriginalGriff 27-Oct-14 4:19am

Yes, generally we are.
But that doesn't mean we are here to do your work: we are more than willing to help people, but we do insist that they try to help themselves, and you have shown no signs of doing that.

Instead, it looks like you have found some code (in a language you don't know) that might do what you want, and are trying to get someone (who doesn't know what the code should do) to translate it for you so you can "bolt it in" and use it.

That isn't what we are here for. If we were, we would spend our entire time doing other peoples work for them for free, while they got paid for sitting there twiddling their thumbs. That isn't a good situation for anyone, except the very lazy!

So no: try it yourself. Or if you can't because you don't know what python is, or how it works, then find some code you do understand that does what you want it to!
