Plotting Polynomial With Given Coefficients

I'm trying to plot a polynomial with coefficients given in array: input: [an,a(n-1),...,a0] output: plot of polynomial anx^n + a(n-1)x^(n-1) + ... + a0 I would like to use matp

Solution 1:

If you are using Julia's Polynomials package then something like this pattern will work:

p = Poly(reverse(ais)) # Poly wants [a0, a1, ..., an] xs = linspace(a, b, 100) # fill in a, b plot(xs, p.(xs))

If you are using Plots, the last two lines could be plot(x->p(x), a, b).
