Matlab Built-in Polynomial Interpolation: polyfit

The basic function-call is p=polyfit(x,y,m), where x is a vector of �� independent values, y is the corresponding vector of �� dependent values and �� = �� − 1. The function returns the coefficient vector of the (�� − 1)-order interpolation polynomial.

What is polynomial interpolation?

Polynomial interpolation is a method of estimating values between known data points. When graphical data contains a gap, but data is available on either side of the gap or at a few specific points within the gap, an estimate of values within the gap can be made by interpolation.

What are polynomials in MATLAB?

Polynomials are equations of a single variable with nonnegative integer exponents. MATLAB^® represents polynomials with numeric vectors containing the polynomial coefficients ordered by descending power. For example, [1 -4 4] corresponds to x² - 4x + 4.

Interpolation of Coarsely Sampled Sine Function

Define the query points to be a finer sampling over the range of x . xq = 0:pi/16:2*pi; Interpolate the function at the query points and plot the result. figure vq1 = interp1(x,v,xq); plot(x,v,'o',xq,vq1,':.
