Condicionales

Condicional simple



In [5]:

    
a = 2
b = 3
if a < b
    println("a es menor que b")
end









    



a es menor que b



In [6]:

    
a = 3
b = 2
if a < b
    println("a es menor que b")
else a > b
    println("a es mayor que b")
end









    



a es mayor que b

Condicional anidado



In [7]:

    
a = 2
b = 2
if a < b
    println("a es menor que b")
elseif a > b
    println("a es mayor que b")
else
    println("a es igual a b")
end









    



a es igual a b

Operador ternario



In [8]:

    
x = 1
y = 2
println(x < y ? "x es menor que y": "x es mayor que y")









    



x es menor que y

Para crear una matriz usamos un bucle y el comando reshape



In [19]:

    
A = reshape(1:100, (10,10))
