possible_zeros = sort(unique(abs(roots(coeff))); % Roots of the polynomial curve fit - the absolute value is to convert complex roots, and the unique() function turns each complex pair to only 1 point error = polyval(coeff,possible_zeros); % Evaluate the polynomial curve fit at every...
When is the Calculator Necessary? When the function is a lower order polynomial such as a linear or quadratic, a graphing calculator is not necessary. The zeros of these functions be easily found without one. For example, f(x) = 2x+1 is a linear function. You can find the zero of th...
However, finding all the zeros of a set of vector functions in the domain of interest is quite a challenging task. This paper proposes a zero finding algorithm that combines the cell mapping methods and the subdivision techniques. Both the simple cell mapping (SCM) and generalized cell mapping...
I've been told that the method scipy.optimize.newton() will solve complex functions so long as the first derivative is provided. I can't make it work. The documentation for newton() mentions nothing of complex functions. Could someone show me how one would find the roots of a function li...

Quadratic Function (y = ax 2 + bx + c) a, b, and c are called the coefficients. The graph will form a parabola. Each graph will have either a maximum or minimum point. There is a line of symmetry which will divide the graph into two halves. ...

In this article, we report on computations that led to the discovery of a new Lehmer pair of zeros for the Riemann ζ function. Given this new close pair of zeros, we improve the known lower bound for de Bruijn-Newman constant Λ. The Ri... Y Saouter,X Gourdon,P Demichel 被引量:...
