(3) Start with a 4 by 4 matrix A whose entries are integers in the range from 1 to 10 (output A). Add a row on the bottom of A that con sists of the mean of each column of A and assign the resulting matrix to B (output B). Next, add a row to the bottom of A that consists of the sums of the entries down each column of A and assign the resulting matrix to C (output C). Last, add a column to the right of A that consi sts of the sums of the entries across each row of A and assign the resulting matrix to D (output D). Hint you can use MA TLAB functions randi, mean, sum.

Question. Use Python Code Correctly to solve this problem. And, Use all Examples Please. Rotate Image You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. Example 1: Input: matrix = [[1,2,3], [4,5,6],[7,8,9]] Output: [[7,4,1],[8,5,2],[9,6,3]] Example 2: Input: matrix = [[5,1,9,11], [2,4,8,10],[13,3,6,7],[15,14,12,16]] Output: [[15,13,2,5],[14,3,4,1],[12,6,8,9],[16,7,10,11]]
Open Question Question 44 2. If we rotate P(2, 3) with 0=30° in anti- clockwise direction relative to point C(1, 2), we obtain P'. (sin30° =0.5, cos 30° = 0.9) Please finish the following tasks: (1) Write Point P and C coordinates in homogeneous coordinates; (2' ); (2) Write the rotating matrix R in 3*3 format(2' ); (3) Calculate P' with the rotating matrix R and the point C (3' ).
Using matlab do this. Create a row vector of 1’s that has 4 rows. Now create a column vector of 1's that has 4 columns. Using matrix multiplication, multiply both of these to get a 4 x 4 matrix and display the resulting matrix. Please answer it correctly and don't copy from anywhere otherwise it will be downvoted.

Hi. I’m stuck on this question and when I asked an expert I still got it wrong. Please can you help
Given a square matrix of size ?×?�×� that only contains integers, compute the sum of the two diagonals. If the dimension of the square matrix is odd, make sure that you are not double-counting the value at the centre of the matrix. Figure 2: Sum of diagonals. Function specifications Arguments: matrix (numpy.ndarray) →→ input matrix to be used for computing the sum. Return: sum (int) →→ return the sum of the two diagonals. Expected outputs: matrix = np.array([[7, 0, 8], [6, 9, 1], [3, 8, 4]]) sum_of_diagonals(matrix)==31 matrix = np.array([[4, 1, 1, 1], [1, 3, 8, 0], [0, 8, 5, 7], [1, 6, 1, 3]]) sum_of_diagonals(matrix)==33
