Modified Secant method

A modified version of the Secant method that uses one initial guess and a fractional perturbation constant for a faster convergence

It is an open numerical method and a modified or improved version of the regular Secant method. It asks for only one initial guesses and a (fractional) constant. It generally converges to the true root faster compared to the regular Secant method. The user also has an option to choose between %relative error or number of iterations as the termination criterion.
