The Conjugate Gradient (CG) method is an efficient iterative algorithm for solving large, sparse systems of linear equations where the matrix is symmetric and positive-definite. It finds the minimum of a quadratic function by generating conjugate search directions, ensuring convergence in at most steps for an matrix.Solver

This code is a psychrometrics library that calculates the full thermodynamic state of moist air from any two independent properties and pressure. Using ASHRAE equations and iterative methods, it computes dry-bulb temperature, enthalpy, relative humidity, specific volume, humidity ratio, and wet-bulb temperature in SI units.
