Test code:

import arraymancer

type
  HiddenMarkovModel* = object
    states*, symbols*: int
    emission_probabilities*, transition_probabilities*: Tensor[float]

proc new_hmm(symbols, states: int): HiddenMarkovModel =
  # book keeping
  result.symbols = symbols
  result.states = states

  # random initialization
  result.emission_probabilities = randomNormalTensor[float]([states, symbols])
  result.transition_probabilities = randomNormalTensor[float]([states, states])

  # 

var hmm = new_hmm(5, 3)

discard hmm.emission_probabilities.mabs()
echo hmm.emission_probabilities

Result:

Ugh, mabs isn't even supposed to return a value/needs discard :/
