FormulaLab is under development, and NOT stable now!

FormulaLab is a Python package that mathematically derives new formulas, searches in formulas, and connects your project code to Formulas Database (FD). FD is a smart and efficient way to list, reference, remark, and organize all of your collections of formulas in one place. FD can be connected to as many projects as you want - where editing and inserting is being done only once for all. The formulas in the FD does not have to be rewriten in different forms, one form is enough, and the rest is being derieved by FormulaLab. For example, Area = Pi * radius^2, if you ask for the radius, FormulaLab will solve it for you - no need for repetition in the FD which is very convienient and time saving when you have many equations.

• Students who are working with many formulas and trying to derive and connect them to solve problems and study smartly.
• Scientists and engineers who are working on research that requires a wide range of formulas to work with, search for, and reference to.
• Developers who want to keep all of their math/physics/... formulas at one place for better maintenance and debugging.

FormulaLab depends on:

• python +3.4
• Sympy
• Pandas
• NumPy

To install FormulaLab:

pip install FormulaLab

>>> import FormulaLab as fl

>>> Physics_formulas = ['F = m*a', 'v = a*t']
>>> phy_search = fl.FormulaSearch(data=Physics_formulas)
>>> phy_search
   ID  Formula       Args
0   1  f = m*a  [m, a, f]
1   2  v = a*t  [a, v, t]

# Now, say you want to derive F as a function of t
>>> Force = phy_search.derive('F', 't')
>>> Force
[m*v/t]

# Now, you want to convert it to a python function
>>> Force_py = phy_search.function(Force[0])
>>> Force_py(m = 2, v = 3, t = 2)
3.0

# Now, you want to find the the value of "t" in a direct search (no subtitution)
>>> phy_search.find('t')
[v/a]

>>> phy_search.find('a')
[F/m, v/t]

# What if you want "a" as a function of "t" and "v", only in a direct search:
>>> phy_search.find('a', ['t','v'])
[v/t] 

# Now, you want to find `a` from the first equation that has ID=1
>>> phy_search.find('a',id=1)
[f/m]
