Given two 2x2 matrices:
M=1 21 1,N=-1 2 1 -1

(a).Verify multiplication of M x N mod 26 = N x M mod 26 = I (identity matrix)

(b). Use Hill cipher to encrypt the message EXAMS

Expert Solution

We know that what is identity matrix, that identity matrix is the matrix whose diagonal elements are always 1.Below are the images for both answers a) and b) .

Divide and Conquer (Strassen’s Matrix Multiplication) Given two square matrices A and B of size n x n each, find their multiplication matrix. Naive Method Following is a simple way to multiply two matrices. void multiply(int A[][N], int B[][N], int C[][N]) { for (int i = 0; i < N; i++) { for (int j = 0; j < N; j++) { C[i][j] = 0; for (int k = 0; k < N; k++) { C[i][j] += A[i][k]*B[k][j]; }...

Consider the nonlinear equation f(x) = x3− 2x2 − x + 2 = 0. (a) Verify that x = 1 is a solution. (b) Convert f(x) = 0 to a fixed point equation g(x) = x where this is not the fixed point iteration implied by Newton’s method, and verify that x = 1 is a fixed point of g(x) = x. (c) Convert f(x) = 0 to the fixed point iteration implied by Newton’s method and again verify that...

Given two functions, M(x, y) and N(x, y), suppose that (∂N/∂x − ∂M/∂y)/(M − N) is a function of x + y. That is, let f(t) be a function such that f(x + y) = (∂N/∂x − ∂M/∂y)/(M − N) Assume that you can solve the differential equation M dx + N dy = 0 by multiplying by an integrating factor μ that makes it exact and that it can also be written as a function of x + y,...

create a function in matlab that sums two m x n matrices using nested loops, then returns result into a new matrix. Use nesed for loops to add matrices piece by piece. Basically means, dont program simply A+B Function should perform error check to make sure both matrices have same number of rows/ columns.
