Project 5 Cubic Spline (due on: April 12) Given the following data point: (-2, 13), (-1, 5), (0, 7), (1, 12), (2, 29), using cubic spline interpolation method to find out Sz) in (-2,2). Plot the graph to show data points and the piecewise polynomial values. Note: You may use Matlab, C/C++, Fortran, Linux shell script etc. for your coding/program/script. You may write the project in C, , Fortran, Java, or matlab, etc. Submit your code along with your result screenshot through moodle
