Performs arbitrary-order finite-difference differentiation of a user-supplied row or column vector. Uses central finite-difference stencils in the middle and sided stencils of the same order of accuracy on the sides.
Syntax
dx=fdvec(x,npoints,order)
Arguments
x - column or row vector to be differentiated
npoints - number of points in the finite difference
stencil
order - order of the derivative required
Outputs
dx - column or row vector with the derivative
