Function name interpolate_spline
Input an array of x values, an array of y values
Outputa matrix with 3 columns and 1 rows where is the length of x (or produce an error if an issue is encountered)
Example
interpolate_spline([1,2,3], [2,6,8]) generates the matrix [2 6 -2; 6 2 0]
Hint 1 : You will need to solve a system of linear equations to get all the values. You do not need to program your own Gauss elimination to do this. Just use Matlabs linsolve command. Given a system of equations of the form = , you would use x =linsolve(A, b)
Hint 2 : The system of equations that appears in the spline equation only has non-zero values on 2 diagonal lines. You can use Matlabs diag command to help construct this matrix. Check the diag help page for more information
Hint 3 : It is possible to meet core requirements without any looping whatsoever. You can use loops if you want, but remember Matlabs array math.
Write a function that interpolates a set of data points using a quadratic spline and outputs a table of coefficients used for the spline fit (a in column 1, b in columns 2, c in column 3) Check to make sure that the same number of x and y data points have been provided (can be any number of data points) Given a set of (xi,y,) points, recall the quadratic spline fit process: 1. 2.
