Function for canculating π

I would want to ask,which is the function,which can canculate the number π from series of Leibniz and 2 of Euler and the error |y- π| ?

THere is no such built-in function. Write your own: LINK

This one is for Leibniz

N = 100; % number of terms
den = 1:2:2*N-1;
signs = (-1).^(0:N-1);

terms_leibniz = 4./den.*signs;
pi_leibniz = cumsum(terms_leibniz);
err_leibniz = abs(pi-pi_leibniz);

plot(pi_leibniz);
hold on
yline(pi);

This one is for Euler

N = 100; % num terms
terms_euler = 6./(1:N).^2;
pi_euler = sqrt(cumsum(terms_euler));
err_euler = abs(pi-pi_euler);

plot(pi_euler);
hold on;
yline(pi);
