Write a method that sums all the numbers in the major diagonal in an n x n matrix of double values using the following header: public static double sumMajorDiagonal(double[][] m) Write a test program that first prompts the user to enter the dimension n of an n x n matrix, then asks them to enter the matrix row by row (with the elements separated by spaces). The program should then print out the sum of the major diagonal of the matrix.

Write a program that prompts the user to enter the length of a square matrix, randomly fills in 0s and 1s into the matrix, prints the matrix, and finds the rows, columns, and major diagonal with all 0s or all 1s.

Problem2: A square matrix can be represented by a two-dimensionalarray with N rows and N columns. You may assume a maximum size of 50 rows and 50 columns. 1. Write an algorithm MakeEmpty(n), which sets the first n rows and n columns to zero. 2. Write an algorithm Add(M1, M2, M3), which adds two matrices M1 and M2 together to produce matrix M3. 3. Write an algorithm Subtract(M1, M2, M3), which subtracts matrix M2 from matrix M1 to produce matrix M3. 4. Write an algorithm Copy(M1, M2), which copies matrix M1 into matrix M2.

Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n)Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix.

Write a program that randomly fills in 0s and 1s into a 4-by-4 matrix, prints the matrix, and finds the first row and column with the most 1s. Here is a sample run of the program:   0011            0011            1101            1011              The largest row index:  2    The largest column index:  3

Multi Dimensional Arrays in C Program Ask the user for the number of rows and columns of a two-dimensional array and then its integer elements. Then, ask the user for another integer value which represents a boogeyman. A boogeyman is a value that we intend to find from a given array. Find and output the coordinates of the boogeyman by this format: "BOOGEYMAN LOCATED AT ROW {row_number}, COLUMN {column_number}!" Input 1. One line containing an integer for the number of rows 2. One line containing an integer for the number of columns 3. Multiple lines containing at least one integer each line for the elements of the array Sample 1 4 2 3 9 1 2 3 4 2 1 1 9 2 8 3 4. One line containing an integer for the boogeyman's value Output Print the row of the position first and then the column of the position. Note that the row and the column is 0-based (i.e. it starts at 0 and not at 1). It is guaranteed that the boogeyman exists and only once in the 2D array. Enter# of rows: 4 Enter…

Write a method that returns the sum of all the elements in a specified column in a matrix using the following header: public static double sumColumn (double[][] m, int columnIndex) Write a (test) program that reads a 3-by-4 matrix and displays the sum of each column. Here is a sample run: Enter a 3-by-4 matrix: 1.5 2 3 4 5.5 6 7 8 9.5 1 3 1 Sum of the elements at column 0 is 16.5 Sum of the elements at column 1 is 9.0 Sum of the elements at column 2 is 13.0 Sum of the elements at column 3 is 13.0

Java Program - Functions with 2D Arrays Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space.   In the main function, write a program that asks for integer input to be assigned on a 3 x 3 array and call the function displayElements to print the contents on the next line. Input 1. Multiple lines containing integer each line Output R1C1: 1 R1C2: 2 R1C3: 3 R2C1: 4 R2C2: 5 R2C3: 6 R3C1: 7 R3C2: 8 R3C3: 9 1 2 3 4 5 6 7 8 9

Q2: In this question, you will write a Python function to compute the Hadamard product of two matrices. The Hadamard product is the "component-wise" product of two matrices. That is, each entry of the product matrix is equal to the product of its corresponding entries of the input matrices. Here is an example: a11 a12 a21 a22 a23 a31 a13 SH a32 033 A b11 b12 b13 b21 b22 b23 b31 b32 b33. B = [an bu a21 b21 a31 b31 a12 b12 a22 b22 a32 b32 a13 b13 a23 b23 a33 b33. Hadamard product of A and B Write a Python function to compute the Hadamard product of two matrices as follows. a) The inputs to the function are two matrices. b) The function should check whether the two matrices have the same size. If not, it should print "The input matrices are not of the same size". c) If two matrices are of the same size, the function computes the Hadamard product and returns the answer. Use for loops to compute the Hadamard product.
