single dimension array smoothing

[danielp0]

does anyone know of a quick way that I can smooth a line graph ?

thanks

You could low-pass filter it. Matlab has many filter design tools, but a simple moving average is often enough:

b=ones(1,n)/n;
smoothed=filter(b,1,rough);

n is the length of your moving average window.

This seems to work fine, thanks. I was looking into using mean, but this is quicker.

the only thing I found is that it shifts the data a bit. but that's not really a problem.

Thanks
