Приведенный ниже код приводит к следующей ошибке:

"Неверные данные проверки. Предикторами должен быть массив последовательностей ячеек N-1, где N - число последовательностей. Все последовательности должны иметь то же измерение элемента и хотя бы один временной шаг. "

Моя проверка следующая: {{24381 × 1 ячейка} [24381 × 1 категориальная]} мои данные об обучении следующие: {{12000 × 1 ячейка } [12000 × 1 категорический]}

TestDataTrainx является двойным 21x72.

Я не вижу, чем мой пример отличается от примера Matlab здесь
