How to fit a smooth curve inside an edge while plotting a 2D figure

Hi,

I have a 2D plot with an edge, I would like to remove the edge as shown in the figure attached and replace with a smooth curve inside (red curve). Could someone provide a good solution.

thanks.

You can smooth the y values:

ySmoothed = conv(y, ones(1, 51), 'same');

Change the 51 depending on whether you want more or less smoothing, but keep it an odd integer.
