Polynomial roots - MATLAB roots
www.mathworks.com › help › matlabUse the poly function to obtain a polynomial from its roots: p = poly (r) . The poly function is the inverse of the roots function. Use the fzero function to find the roots of nonlinear equations. While the roots function works only with polynomials, the fzero function is more broadly applicable to different types of equations.
Root of nonlinear function - MATLAB fzero
www.mathworks.com › help › matlabx = fzero (fun,x0) tries to find a point x where fun (x) = 0. This solution is where fun (x) changes sign— fzero cannot find a root of a function such as x^2. x = fzero (fun,x0,options) uses options to modify the solution process. x = fzero (problem) solves a root-finding problem specified by problem. [x,fval,exitflag,output] = fzero ...
