% This function is defined for both up and down sampling of
% any signal x[n]:: [y m]= udnsample(x,n,M)
% ===========================================================
% |***For Down Sampling::If downsampling factor is 2 then M=2|
% |***For Up sampling::If upsampling factor is 2 then M=1/2 |
% ============================================================
% x is the input signal and n is axis for it.
% length(x) must be equal to length(n) and
% n must contain origin i.e. n=[0 1 2 3]
% n=[-1:5] both contains 0(origin of axis).
