Ejercicios en MATLAB!!!

%Ejercicio 1
clear all
for i=1:3
a = i^(1/3);
b = log(2*i);
c = sin(i);
A(i)=a + b -c;
B(i)=[(i^(1/3))+log(2*i)-sin(i)];
end
format long
sum(A)
sum(B)
%Ejercicio 2
for i = 1:3
a = tan(pi*i);
b = exp(i);
C(i) = a^2 - b;
D(i)=[(tan(pi*i))^2-exp(i)];
end
format short
sum(C)
sum(D)
