Question
Here is what I need to do.
1, allow user to input the interval of interpolation ([a, b]), number of interpolation points (n), and a total of 4 functions(f, h,g, and i)
2. create a divided difference table and find the coeeficients
3. plot the error between original function and interpolant.
I have everything up where i need to plot the error because i cant figure out how to make aloop to build the polynomial with the coeeficients that I have found so I can evaluate at some dense mesh interval to plot agianst my original functions.
Say I have a n coeeficients in an vector called C decending order of powers. Sio my polynomial will look like this
C(1)*t^n + C(2)*t^n-1 + .... + C(n)*t^0
Can someone help me make a loop for this for any size n?
