this implementations use a vectorized form of the following formula to calculate the binomial coefficients
convolution matrix using the binomial coefficients , can be seen as sum of a toeplitz matrix and a lower triangular matrix filled with ones
the product of the matrix and the sample function results in the approximation of the derivative
