moving average through filter

y=mvaveragec(x,N)

function y=mvaveragec(x,N)
%MVAVERAGEC signal smoothing through the moving average method.
% Y = MVAVERAGEC(X,N) Quickly smooths the signal X via averaging each
% sampling with the previous and afterwards N samples.
%
% Example:
% t = 2*pi*linspace(1,1);
% xn = cos(x) + 0.25  0.5*rand(size(x));
% xs = mvaveragec(xn,4);
% plot(t,xn,t,xs), legend('noisy','smooth'), axis tight
