Basically ive got to design and develop a software for computing a polynomial function involving a set of data points. Ive got to use an algorithm based on the lagrange interpolation method. I know it should involve two loops inside the code. What ive been told is that "The input to the program should consist of a given number of data points 'n', the values of the independent variables 'Xi' and the dependent variable 'F(Xi)' at each point, and the 'X' value for interpolation. The data points will be stored in arrays "x" and "f", and the 'X' value for interpolation is stored in "x_value". Your program should be able to determine 'F(X)' using this information." Anyone got any ideas?
