thanks so much AlephZero,
Could you check If it is correct ?
function int = chebquad(funct,accuracy)
f = inline(funct);
old_int = inf;
for n=1:1000
x = cos(((2*(1:n) - 1)/(2*n))*pi);
w = pi/n;
fx = f(x);
int = sum(w.*fx);
if abs(int_old-int) < abs(tol*int),
converge='y'...
Hello, anyone knows where y can find a program to compute the integral
∫ ( from -1 to 1) f(x)/ √(1-x^2) using the Gauss-Chebyshev quadrature, on matlab?
Thanks!
Hi!
Homework Statement
1. Substituting an ansatz \Psi(x)= u(p) e^{(-i/h) xp} into the Dirac equation and using \{\gamma^i,\gamma^j\} = 2 g^{ij}, show that the Dirac equation has both positive-energy and negative-energy solutions. Which are the allowed values of energy?
