The test suite checks for equality, but different techniques have small numerical differences. The test suite should allow for these differences, as it eliminates many solutions that are correct.

This problem has been updated to check against a small error value rather than for equality.

d1=sqrt((X(2)-X(1))^2+(Y(2)-Y(1))^2); %distancia de A hasta B
d2=sqrt((X(3)-X(1))^2+(Y(3)-Y(1))^2); %distancia de A hasta C
d3=sqrt((X(3)-X(2))^2+(Y(3)-Y(2))^2); %distancia de B hasta C

s=(d1+d2+d3)/2; %Semiperimetro
y=sqrt(s*(s-d1)*(s-d2)*(s-d3)) %Fórmula de Herón
