Makes prettier axes (plots)

It changes the current axis to arrows, making your plot more visually appealing.

It changes the current axis to arrows, making your plot prettier and ready for insertion in presentations or documents where precision is less important than the concept.

Example:

f = @(x) (exp(-pi*x.^2));
x = -2:0.05:2;
plot(x,f(x),'LineWidth',2);
axis([-2 2 0 1.2])

% Default
% pretty_axis;

% With labels and not centered
data.xlabel = '$x$';
data.ylabel = '$f(x)$';
data.fontsize = 20;
data.axis_centered = false;
pretty_axis(data);
