Plus matrix

Total A + B of two matrices of the same size NxM A and B is a matrix with elements of the same size in the corresponding position by the sum of two elements of each matrix corresponding: (A + B)i,j = Ai,j + With a,j, with 1 ≤ i ≤ N and 1 ≤ j ≤ M. Threads: Enter two matrices have the same size NxM. compute

Check symmetric matrix

Square matrix is ​​a matrix of rows and columns of equal. Matrix NxN square matrix called Career N.Ma symmetrical ball is a square matrix with the transposed matrix of it, or AIJ = Aji Recommended Posts: Enter into a square matrix of degree n.

Matrix transposition

If A is a matrix of n x m in size with values ​​aij in row i, column j, the matrix transpose matrix B = AT m x n size with values: bij = aji Example: Threads: For matrix A n x m size. Find the matrix transpose of the matrix A. Input: The first line contains 2

Check array symmetry

Threads: For an array of n integers. Check if the array is mirrored. Plate symmetric arrays when writing in the forward or reverse are identical results. Input: The first line is an integer n. The second line 2 n is an integer array, the number of ways
