Add tensors

(a <- torch$tensor(seq(1, 10)))
(b <- torch$ones(10L))
(c <- torch$linspace(0.1, 1.0, steps = 10L))

a$add(b) == a + b

a + c == c$add(a)

a + b + c

Subtract

a - c == a$sub(c)

a - b - c

Multiply

a * b == a$mul(b)

a * b * c

Divide

# division by integers not accepted
a$dtype
c$dtype
torch$div(a, c) == a / c

b$dtype
a / c / b

Exponentiation

2^a

a^(1 / c)

Logarithms

c$log10()

c$log()
