• MATLAB has built-in curve fitting functions that allows us to create empiric data model. • It is important to have in mind that these models are good only in the region we have collected data. • Here are some of the functions available in MATLAB used for curve fitting:-polyfit()-polyval()

Use polyval with four inputs to evaluate p with the scaled years, (year-mu(1))/mu(2). Plot the results against the original years. ... Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool.

y = polyval(p,x) returns the value of a polynomial of degree n evaluated at x . The input argument p is a vector of length n+1 whose elements are the ...

y = polyval(p,x) evaluates the polynomial p at each point in x. ... Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool. This function fully supports thread-based environments.

y = polyval(p,x) returns the value of a polynomial of degree n evaluated at x. The input argument p is a vector of length n+1 whose elements are the coefficients in descending powers of the polynomial to be evaluated. x can be a matrix or a vector. In either case, polyval evaluates p at each element of x. y = polyval(p,x,[],mu) uses in place of .

y = polyval(p,x) returns the value of the polynomial p evaluated at x . Polynomial p is a vector whose elements are the coefficients of a polynomial in ...

Polyfit is a Matlab function that computes a least squares polynomial for a given set of data. Polyfit generates the coefficients of the polynomial, which can ...

Why we Use Polyval Matlab? ... There are various functions and commands which are used to find out the roots of polynomials but other methods fail to evaluate ...
