diffCenterVar
% [dx, ddx] = diffCenterVar(t,x);
%
% Computes first and second derivatives of x(t)
% --> Second-order accurate
% --> Works for non-uniform grid
%
% INPUTS:
% t = [1,m] = time grid
% x = [n,m] = function values for each point on the grid
%
% OUTPUTS:
% dx = [n,m] = first derivative of x
% ddx = [n,m] = second derivative of x
%
% NOTES:
% This function works by locally fitting a quadratic curve between each
% set of three points. See Derive_Eqns.m for details.
