math.import(require('mathsjs-translate'));

// translations
let matlabExpr = math
    .parse('min(x1,x2,x3) + log(x,b)')
    .translate(math.expression.translate.to.matlab)
    .toString();
console.log(matlabExpr);
// min([x1, x2, x3]) + log(x) / log(b)

// get
let functions = math
    .parse('min(x1,x2,x3) + log(x,b)')
    .getFunctions();
console.log(functions);
// ['min', 'log']
