Using Matlab

Programming condition

1.Polyfit() and polyval() are not allowes to used

2. left devision(\) and inv() are not allowed to use in Matlab code

3. To fit curve with data . You may require to solved system of equations. In case of solving system of equations, student are free to apply guass elimintion ,Lu decomposition , Jacobi iterative method , or Gauss seidel method to solved the system of equations.

Have a great day .
