python # Initialize a 6x6 matrix with all elements as 0 matrix = [[0 for _ in range(6)] for _ in range(6)] # Fill in the matrix for i in range(6): # Iterate over rows for j in range(6): # Iterate over columns if i > j: matrix[i][j] = 3*j - 4*i else: matrix[i][j] = 0 # Print the matrix for row in matrix: print(row)

Vectors store a linear arrangement of values, accessed by a single index. Two-dimensional arrays store a tabular arrangement of values, accessed by two indexes, for example matrix[i][j], where i is the row index, and j is the column index. A common two-dimensional array that you should have seen early on in your education is a multiplication table. For example, here is the multiplication table up to 5 x 5:   1 2 3 4 5 1 1 2 3 4 5 2 2 4 6 8 10 3 3 6 9 12 15 4 4 8 12 16 20 5 5 10 15 20 25     Write a program that asks the user for the number of rows and columns for a multiplication table and prints out the corresponding results.

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.
