Webnumpy.roots(p) [source] # Return the roots of a polynomial with coefficients given in p. Note This forms part of the old polynomial API. Since version 1.4, the new polynomial API defined in numpy.polynomial is preferred. A summary of the differences can be found in the transition guide. WebYou can use the root function as input to Symbolic Math Toolbox functions such as simplify , subs, and diff. Simplify an expression containing root using the simplify function. syms x r = root (x^6 + x, x, 1); simplify (sin (r)^2 + cos (r)^2) ans = 1 Substitute for parameters in root with numbers using subs.
