Take a look at the text function with the latex interpreter. Here's a working example:
plot(0:.1:pi,sin(0:.1:pi))
text(pi/2,.9,'$$t = \frac{\pi}{2}$$', ...
'Interpreter','latex', ...
'FontSize',14, ...
'HorizontalAlignment','center')
There's also the annotation function if you want to add other shapes but that's a bit more complex.

In the text call, specify 'Interpreter','latex', however the more interesting part of this was (finally) figuring out how to correctly place the annotation objects.
This combines both of them —
x = linspace(-2, 1, 250);
y = 3.5*exp(-(x+1).^2*150);
figure
plot(x, y, '--k')
ylim([-1 4])
yline(0, '-k')
text(0, 3.5, '$\it{t=0}$', 'Interpreter','latex', 'FontSize',15, 'Horiz','center')
text(-1.5, 1.75,'$\alpha\_$', 'Interpreter','latex', 'FontSize',15, 'Horiz','center')
xs = @(x,pos,xlim) pos(3)*(x-min(xl))/diff(xl)+pos(1);
ys = @(y,pos,ylim) pos(4)*(y-min(yl))/diff(yl)+pos(2);
xl = xlim;
yl = ylim;
pos = gca().Position;
xs = @(x,pos,xlim) pos(3)*(x-min(xl))/diff(xl)+pos(1); % 'x' Annotation Position Function
ys = @(y,pos,ylim) pos(4)*(y-min(yl))/diff(yl)+pos(2); % 'y' Annotation Position Function
% Qy = ys([2.5 3.5],pos,ylim)
% Qx = xs([1 1]*-1.5,pos,xlim)
annotation('arrow', xs([-1.5 -1.5],pos,xlim), ys([1.5 0],pos,ylim))
annotation('arrow', xs([-1.5 -1.5],pos,xlim), ys([2.0 3.5],pos,ylim))
I am not certain what the other curves represent, so I did not draw them.
