In using quadratic spline interpolation, finding the coefficients requires a matrix-vector notation where the vector of unknowns can be found by inversing the matrix and multiplying it to the left-hand side of the notation. Given the table shown below, find the values of the matrix-vector notation. The size of the matrix should be 15 x 15 and those of the vectors should be 15 x 1 4. Velocity () 0 200 400 600 800 1000 Time (t) 10 15 20 25
