Numpy is a python wrapper around a C implementation of matrix math. That means it uses pointer math for speed. This is very easy for a virus to exploit. Your C professor didn't warn you about this? I would rather have a pure Python implementation of the same features and be able to tell my client it's secure. Also, if you thought that programming language implementations of floating point arithmetic weren't error prone then your Professors omitted essential information.
With numpy you have no control over how mathematical operations are done and no control over the type translation from C types to Python native types. Both can introduce errors that you have no information regarding. A pure Python implementation can monitor and control both the particular mathematics done and the particular types and type translations used.
You gain security, precision, and better estimate of error by implementing in pure Python.
