compute the indefinite integral

how can I compute the indefinite integral of an anonymous function?

f=1010;
d= 0:0.0001:8;
z = @(d) sawtooth(2*pi*f*d+pi,0);

If you are lucky, using the symbolic toolbox and "int".

"sawtooth" is a numerical function.

Thus you will have to compute the indefinite integral from above using pencil and paper.

thank you for your reply

I did compute the integral of the above function symbolically using syms and int and a bunch of heavisides. However, I can't use anything symbolic when I try to import the result in Simulink. I converted the symbolic expression with matlabFunction, but I do not know how to use it in Simulink

I am trying to plot the above function and its integral in Simulink

f = 1010;
z = @(d) sawtooth(2*pi*f*d+pi,0);
dstart = 0.0;
dend = 0.01;
delta_d = 1e-5;
d = dstart:delta_d:dend;
intz = cumtrapz(d,z(d));
hold on
yyaxis left
plot(d,z(d))
yyaxis right
plot(d,intz)
hold off
