I am using this running average function to smooth out dome noisey data.

function y = RunningAvg(x,w)
   wts = ones(1, w) / w
   new = conv(x, wts, 'same');
end

However, when I plot the filtered signal, I get this error massage

Value not a numeric scalar

and it is true that there are some noninterger data in the x_smooth. Is there anyway to override that?

Yes, it was that line

plot(t,x_smoothed,'linewidth','2')

that we were looking for.

plot(t,x_smoothed,'linewidth','2')

Line widths must be numeric.

plot(t,x_smoothed,'linewidth',2)
