Can't the inner product be used in Julia 1.0.2?

Asked 2 years ago, Updated 2 years ago, 107 views

Now, if you use dot in the array below,

n=3
psi = zeros (Float 32, n, n, n, 6)
psi[1,1,1:] = [1/sqrt(2), 1,1,1,1,1,1]
psi[1,1,1:].*psi[1,1,:]
dot(psi[1,1,1,:], psi[1,1,:])

Calculating that

UndefVarError: dot not defined
