Example 1 shows the Mat lab program to solve this problem. Let us consider two equations eq1 = 4 x^2 + 6 x + 3 and eq2 =, eq2 is location of points. Examples to Implement Polyval MATLABÄ«elow are the examples mentioned: Example #1 And if we want to fit or use multiple values or ranges then we can use polyfit command. It also helps to evaluate the definite integral of polynomials. This vector represents coefficients of the polynomial. Let us assume one equation x 1 = 9 x^3 + 5 x^2 + 4 x + 9 at points 4, 5, 3, 2 then it will create one vector. If we want to find out the roots of polynomials at different locations then we use polyval. in such cases polyval plays a vital role. There are various functions and commands which are used to find out the roots of polynomials but other methods fail to evaluate roots or solutions of higher degree polynomials. = polyfit(range ,eq1, 1): Output variable names = polyfit (range, polynomial coefficients, 1).Op = polyint(eq1): output variable name = polyint(coefficients of polynomial).
