Delphi library that provides an easy way to evaluate mathematical expressions, calculate symbolic derivatives & integration, solving non linear equations, approximation function calculation and more...

TMS Analytics & Physics Pack is a Delphi library for developers that contains special classes to work with analytical expressions in Delphi programs - parse expressions, calculate expression values with multiple parameters, expression based derivatives & integration calculation and so on. In addition, it offers approximation function calculation, solving differential and non-linear equations. TMS Analytics & Physics Pack allows using various physics concepts (such as physical quantities, units of measurement, ...) in Delphi programs.
