fplot tolerance parameter error

x = inline (' (1/e) * ((t>0) & (t<=e))', 't', 'e' );

e = 1/100;
t1 = -1;
t2 = 5;
t = [t1, t2];

fplot (x, t, 1e-5, 1000, '-', e)

Warning: The tolerance parameter input to fplot has been removed.

Please begin to use anonymous functions rather than inline funcitons —

x = @(t,e) (1/e) .* ((t>0) & (t<=e));

e = 1/100;
t1 = -1;
t2 = 5;
t = [t1, t2];

fplot (@(t)x(t,e), t, 'MeshDensity',500)

set (gca, 'FontSize',16)
xlabel('t')
ylabel('p_\epsilon(t)')
axis ([t -0.1 1.1/e])
title('Pulse function,\epsilon = 1/100')

It is necessary to increase the 'MeshDensity' in order to show the pulse. The values of ‘t’ will otherwise ‘skip over’ the interval of interest.

Thank you!

As always, my pleasure!
