How can I write this for Matlab?

I am doing a project for an engineering class and I modified this code for Javascript, but i need to use it in matlab. Does anyone know how they would best write this in Matlab? Thank you!

function presses(phrase) {
  var phrase = phrase.toUpperCase();
  var result = 0;
  for (i = 0; i < phrase.length; i++) {
    if (phrase[i] == "7" || phrase[i] == "9") {
      result += 5;
    } else if (phrase[i] == "S" || phrase[i] == "Z" || phrase[i] == "2" || phrase[i] == "3" || phrase[i] == "4" || phrase[i] == "5" || phrase[i] == "6" || phrase[i] == "8") {
      result += 4;
    } else if (phrase[i] === "C" || phrase[i] === "F" || phrase[i] === "I" || phrase[i] === "L" || phrase[i] === "O" || phrase[i] === "R" || phrase[i] === "V" || phrase[i] === "Y") {
      result += 3;
    } else if (phrase[i] === "B" || phrase[i] === "E" || phrase[i] === "H" || phrase[i] === "K" || phrase[i] === "N" || phrase[i] === "Q" || phrase[i] === "U" || phrase[i] === "X" || phrase[i] === "0") {
      result += 2;
    } else {
      result += 1;
    }
  }
  return result;
}

if ismember(phrase(i), '79')
   result = result + 5;
elseif ismember(phrase(i), ['SZ' '2':'6' '8'])
    result = result + 4;
elseif ismember(phrase(i), 'CFILORVY')
    result = result + 3;
elseif ismember(phrase(i), 'BEHKNQUX0')
    result = result + 2;
else
    result = result + 1;
end

Hi Walter, I ran this and got an error saying that phrase was undefined for me, in Matlab do you know where i need to go to import this?

[Walter Roberson]

phrase = char(randi(0+['0' 'z'], 1, 20))

phrase = '8lwiCEr>f:pJuVX4tjG>'

presses(phrase)

ans = 41

function result = presses(phrase)
    phrase = upper(phrase);
    result = 0;
    for i = 1 : length(phrase)
        if ismember(phrase(i), '79')
        result = result + 5;
        elseif ismember(phrase(i), ['SZ' '2':'6' '8'])
        result = result + 4;
        elseif ismember(phrase(i), 'CFILORVY')
        result = result + 3;
        elseif ismember(phrase(i), 'BEHKNQUX0')
        result = result + 2;
        else
        result = result + 1;
        end
    end
end
