This function allows to calculate the coefficients weighting the function values at different points according to central finite differences theory.
It should be noted that the points are equispaced.
These coefficients according to specific equations cited in the attached function file, allow to estimate the derivative of any order id and of any order of accuracy ac
The function has 2 inputs consisting of the wanted id and ac, and has two outputs that are np the number of points and co the coefficients.
This matlab function uses the solve function from symbolic math toolbox and has been created with Matlab R2016-student.
