Возникла проблема при использовании объединения матриц функцией stack, когда одна из матриц является зеркально другой. Если просто использовать функцию stack, то все работает, но стоит включить её в состав переменной, как возникают проблемы (см. вложение - Stack-reverse.sm (8kb) downloaded 14 time(s).).

Похоже какой-то глюк. Нажимаю после строчки "k:stack(m,m2)" знак "=" и результат меняется
