When you need to compute the value of a polynomial at some point, you can use the built-in MATLAB function ‘polyval’. The evaluation can be done for single numbers or for whole arrays. For example, to evaluate. at s = 1,2, and 3, type »a=[1 2 1]; »polyval(a,[1:3]) ans = 4 9 16. to produce the vector of values A (1) = 4, A(2) = 9, and A(3 ...

would be represented in Matlab as: >> y = [1 0 0 0 1] ii) Evaluating a Polynomial. You can find the value of a polynomial using the polyval function. For example, to find the value of the above polynomial at s=2, >> z = polyval([1 0 0 0 1],2) z = 17 iii) Roots of a Polynomial. You can also extract the roots of a polynomial.

Are the roots where you expect them to be? The function 'polyval' will be useful for this exercise.-There is a way to set the aspect ratio of a plot to 1. Find out how to do this. 7 - Relational Operators, Logic and Control Flow. Matlab is very similar to C in its implementation of relational and logical operators.

POLYVAL - Polynomial evaluation. If V is a vector whose elements are the coefficients of a polynomial, then POLYVAL(V,s) is the value of the polynomial evaluated at s. If s is a matrix or vector, the polynomial is evaluated at all points in s. The following is an example MATLAB curve fit sequence using polyfit and polyval.

The output from MATLAB is a vector with the coefficients of the polynomial from highest to lowest. 3. (3 points) Make a graph of the polynomial. In MATLAB you can use the following to make the graph. m1 = linspace(0, 11, 111); Tpoly = polyval(p, m1); plot(m, T, '*', m1, Tpoly, ':'). Based on this graph do you see any problems in this polynomial ...
