  Numerical physics has gained a lot of importance in the last decade, its
efficiency being motivated and sustained by the growth of computational power.
This paper presents a concept that is to be developed in the next few years:
OpenPh. OpenPh is a numerical physics library that makes use of the advantages
of both open source software and MATLAB programming. Its aim is to deliver the
instruments for providing numerical and graphical solutions for various physics
problems. It has a modular structure, allowing the user to add new modules to
the existing ones and to create its own modules according to its needs, being
virtually unlimited extendable. The modules of OpenPh are implemented using
MATLAB engine because it is the best solution used in engineering and science,
providing a wide range of optimized methods to accomplish even the toughest
jobs. Current version of OpenPh includes two modules, the first one providing
tools for quantum physics and the second one for mechanics. The quantum physics
module deals with the photoelectric effect, the radioactive decay of carbon-11,
and the Schr\"odinger equation - particle in a box. The classical mechanics
module includes the study of the uniform circular motion, the forced damped
harmonic oscillations and the vibration of a fixed-fixed string.
