How to draw good looking arrows in Matlab?

I have been trying to draw arrows in Matlab in my figure but they all look terrible. Also, I want my arrowhead to be a solid triangle, not a V.

I tried using the packages available on the Matlab File Exchange: arrow, arrows, arrows3, and probably at least one other one.

I even tried manually creating an arrow in the Matlab figure editor, but when I adjust the line width, the arrow looks like this:

I used the annotation command to create the arrow above:

annotation(gcf,'arrow',[0.621875 0.457916666666667],...
                       [0.205421152030217 0.40755429650614],...
                       'HeadLength',4,'LineWidth',5);

Here's the result trying to use the arrow package available here: Arrow.m (notice how the bottom arrow head is not perpendicular to the line:

I even tried the following and here is the result below (notice the terrible looking arrowhead):

 figure
 plot(1:10, 1:10)
 annotation(gcf,'arrow',[0.621875 0.457916666666667],...
                        [0.205421152030217 0.40755429650614],...
                        'HeadLength',4,'LineWidth',5);

Solution

  • I resorted to installing InkScape and drawing arrows in there. Nothing beat the simplicity and quality.
