Is it in the same place every time? If not, try using imfindcircles() then masking it out. Why does it matter if it's there though?

MATLAB: Undesired gaps in alphashape

The criticalAlpha method computes that you should use an alpha slightly greater than 1 to get all the points in 'one-region'. Giving it a bit extra leeway, I chose to use 1.03:

alpha = 1.03;
shp = alphaShape(x(:), y(:), z(:), alpha);  
crit = criticalAlpha(shp, 'one-region')
plot(shp)

MATLAB: Fplot add an undesired line

The gray line (that is always present (although it changes with the LineWidth parameter) indicates that the function increases or decreases without bound at that point.

There is no direct way to remove it, however you can get the XData and YData values from the fplot function and plot them separately:

figure
h=fplot(@(u) u.*exp(u),[-6,1],'r-','LineWidth',3);
figure
plot(h.XData, h.YData, '-r', 'LineWidth',2)

The gray dashed line is now gone from the second plot.
