Error using plot: Value not a numeric scalar
显示 更早的评论
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

Please provide example inputs (x,w) to your function. There is no y that is returned.

we need to see the plot call

x is a noisy dataset. The plot of x is the following

It appears that w would be expected to be a positive integer. But we still need to see the call to plot()

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)
