Assuming
H_m and t_m are stored in (1 x M )arrays
% Dummy test data
M = 10;
H = rand(1,M);
t = rand(1,M);
P = sum( abs(H(:)).^2 .* [-ones(M,1) +3*t(:) -3*t(:).^2 +t(:).^3]);
t0 = roots(P)
sum(abs(H).^2 .* (t - t0).^3, 2)

Elaborate what? Your orginal equation you post seems fishy to me, not the MATLAB implementation of your equation.
Another fischy fact : the expression only have sum of strictly positive quantities, you cannot expect there is a real root of it. Something is wrong with the maths/physics where you derive the expression/equation.
