N-Code (Numerical Code) is a fortran bundle for the numerical treatment of algebraic and transcendental equations, system of linear algebraic equations, matrix algebra and factorisations (eq. cholesky), eigenvalue problems, interpolation for equispaced and unequally spaced nodes, differentiation, integration, and 1st order and 1st degree differential equations. The code also includes the sub-routine of least squares method and curve fitting tool for graphical measurements. The N-Code is developed on fortran 90 platform, and the python version of the same will be updated soon.
