NumPy :a powerful computing library

In my recently project,we plan to develop a financial system.There are many of mathematical computing in it.For performance reason, we need a high speed,fixable,reliable and efficient library.We estimate many libs ,in the end we decide to use Numpy,we highly recommend it.As the introduce of them:

The fundamental package needed for scientific computing with Python is called NumPy. This package contains:

• a powerful N-dimensional array object
• sophisticated (broadcasting) functions
• basic linear algebra functions
  
• basic Fourier transforms
• sophisticated random number capabilities
• tools for integrating Fortran code.
• tools for integrating C/C++ code.
