pynumwrap
Python package wrapping python and mpmath types behind a common interface.
Installation
Clone the repository and install with the following commands:
git clone https://github.com/petersbingham/pynumwrap.git
cd pynumwrap
python setup.py install
Dependencies
Third party packages:
- numpy
- mpmath
- sympy
Usage
This package just wraps similar functionality in sympy, mpmath and numpy, along with the two types, mpmath and standard python behind a common interface. Not all functionality is currently supported, but can be added as required (please submit a PR). To know which functions are supported look in the pynumwrap/__init__.py file.
The type can be changed by calling the use_python_types and use_mpmath_types functions with the dps passed as an optional parameter. Python types are used as default.
The following example illustrates using the two different types:
>>> import pynumwrap as nw
>>> mat_lst = [[1.,2.],[3.,4.]]
>>> py_mat = nw.matrix(mat_lst)
>>> res = nw.invert(py_mat)
>>> res[0,0]
(-1.9999999999999996+0j) # Standard python type
>>> nw.use_mpmath_types()
>>> mp_mat = nw.matrix(mat_lst)
>>> res = nw.invert(mp_mat)
>>> res[0,0]
mpf('-2.0') # mpmath type
