newton2poly

newton2poly generates the polynomial formula given newton interpolation coefficients and x-coordinate interpolation nodes.

newton2poly generates the polynomial formula given newton interpolation coefficients and x-coordinate interpolation nodes as:
p(x) = c(1) + c(2)*(x-nodes(1)) + c(3)*(x-nodes(1))*(x-nodes(2))...

INPUT:
c -> column vector containing newton polynomial coeffcients from the
function interpN(x, y)
nodes -> column vector containing x-coordinate interpolation points
OUTPUT:
p -> polynomial formula of newton interpolation
