Как отобразить умножение функции? Доброго времени суток
Нужно сделать перегрузку функции, которые перемножают матрицу на матрицу, вектор на вектор, матрицу на вектор и тд
Функции написал, но есть маленькая проблема
После умножений каких либо функций, результата нет на экране
В чем проблема? Как это изменить?using System
