Educational project s21_matrix from organization «School 21».

Implementation of some functions for processing numerical matrices in C programming languages. Develop basic operations with matrices: creation, deletion, addition and subtraction of two matrices, multiplication of a matrix by a number and another matrix, transposition, inversion, search for a determinant.
