Interpolation Polynomial Coding MATlab
I have to write a Matlab function called "interpoly(x,y) which calculates the corresponding interpolation polynomial for given support points (xj,fj) with x=[x1,x2,...,xn] and f=[f1,f2,...,fn] and in interval x[min xj, max xj] plotted. Any method can be used to calculate the interpolation polynomial but I think Lagrange would be the best. One rule is that I can not use "polyfit" command.I have to test the programm with values of fj of the functions f(x)=cos(x) and f(x)=1/(1+x^2) each in the interval [-6,6]....

The error function is a mathematical function that frequently arises in probability and statistics. It also can show up in the solution to some partial differential equations, particularly those arising in heat and mass transfer applications. The error function is defined as 2 e-t dt picture attached This function is actually built-in to MATLAB as the command erf, and here we'll use that function to compute a "true value" with which we can compare results of two interpolation approaches....
