Constructors

CholeskySolver({required List<List<double>> equations, required List<double> constants})
Given an equation in the form Ax = b, A is a square matrix containing n equations in n unknowns and b is the vector of the known values.
CholeskySolver.flatMatrix({required List<double> equations, required List<double> constants})
Given an equation in the form Ax = b, A is a square matrix containing n equations in n unknowns and b is the vector of the known values.
