To interpolate a polynomial using the Newton method in Matlab, you can use the polyfit
function.
Let's say we have a set of data points (x,y) that we want to interpolate using a polynomial of degree n. The steps to perform Newton interpolation in Matlab are:
main.m46 chars3 lines
polyfit
function with the argument n
to obtain the coefficients that define the polynomial of degree n that best fits the data points:main.m33 chars2 lines
main.m44 chars2 lines
Where x_interp
is the point where we want to interpolate the polynomial, and y_interp
is the interpolated value.
Here's an example of how to perform Newton interpolation in Matlab:
main.m471 chars18 lines
This will plot the original data points and the interpolated point at x=2.5 using a polynomial of degree 4.
