use Java Program Assume three matrices of the same size, say matrix A, B and C. Write a program that will add the two matrices A and B and store the sum to C. Matrix addition is done component-wise, i.e., C[i][j] = A[i][j] + B[i][j] where i,j are the row and column index respectively.

Write a program in Java How to enter values from the keyboard and store them in a 4 x 4 matrix, then print them in an organized manner

In python, how do you generate a distance matrix H where in each entry hij, the distance between row i and row j are stored, distance is computed by the inner product <x,y>C := xTCy, where the matrix C is a 3x3 matrix: [3 1 6  1 2 1  6 1 27].  The dataset is a 26x5 matrix and I need to find the distance using the above inner product between each row - I should end up with a 26x26 distance matrix H, where each diagonal entry (i=j) is 0.

1. Write a python program that combines two arrays of the same size one-in-a-row. For instance, if a=[1,2,3,4] and b=[5,6,7,8], the combined array should be [1,5,2,6,3,7,4,8].
