Numpy product of a vector and it's transpose
I have a N x N complex NumPy array U_0 and I have to do manipulation with it :
First, how can I increase the array with zero efficiently ? I can simply copy it into an np.zeros((2N-1, 2N-1)) but maybe you guys know a better method. Thanks to…

Error Simpson's rule for polynomial not equal to 0
I implemented Simpson's rule in Python and tested the error for a cubic polynomial. The error bound of Simpson's rule states that it should be equal to 0, but it is not. Does anybody know why?

if N % 2 == 1:

Is it possible to parallelize this program (Simpson's Rule) in Python?
I am new to the parallelizing paradigm. I already have the algorithm working in its serial form but I can't parallelize it.
I have asked around and some have told me that the way my program is written can't be parallelized.
Here is my serial code,…
