) A binary mxn matrix is a matrix with m rows and n columns, whose entries can be only 0 or 1. How many mxn binary matrices are there?
In a matrix with m rows and n columns, there will be m x n = mn elements.
Each element can be 0 or 1. That is, each element can take any of these two values.
Number of possible mxn binary matrices = 2mn

A ternary matrix is a matrix whose entries are either 0,1 or 2. (a) How many ternary matrices of size mxn (that means, with m rows and n columns) are there? (b) How many ternary matrices of size 5x4 if 10 entries must be 0's, 6 entries must be 1's and 4 entries must must be 2's?
Enter T or F depending on whether the statement is true or false. (Only ONE attempt allowed.) (You must enter Tor F -- True and False will not work.)_______ 1. A matrix with dimensions m by n, where m > n, has fewer rows than columns._______ 2. The 3rd row, 4th column entry of a matrix is below and to the right of the 2nd row, 3rd column entry.
Given a matrix with m rows and n columns, m adjacent numbers are chosen from m rows, where two numbers are adjacent to each other if they are directly connected vertically or diagonally and only one number is taken from one row. Design a dynamic programming algorithm to find the smallest sum of these m numbers. For example, given a 3 by 3 matrix 1 2 3 4 5 6 7 0 2 The sum of three numbers 1, 4,...
how can i solve the system of these magic matrices using matlab software ? Exercice 3. A magic matrix is a square matrix with integer entries in which all the rows, columns and the two diagonals have the same sum. For example, A- 3 5 7 4 9 2 Complete the following magic matrices 17? ?? 3 ? 2 ? 2? ? Do the following steps in each case: 1. Write the system of equations and put it under the...
A standard card deck consists of 52 cards, divided into four groups of 13 cards (called suits: clubs (♣), diamonds (♦), hearts (♥) and spades (♠)). In each suit, the cards have 13 different "faces": A,2,3,4,5,6,7,8,9,10, J, Q, K. (a) in how many ways can I select five cards from the deck? (b) in how many ways can I select five cards from the deck, if all cards must belong to the same suit? (c) in how many ways can...
1. A permutation matrix P is a square matrix obtained by reordering the rows (or columns) of In. (a) Show that any permutation matrix can be written as a product of matrices of the form Pjk, where Pjk is the result of swapping Rj Rk on In. (b) Show that a permutation matrix satisfies the equation PTP In.
Suppose that А is an mxn matrix with independent columns and the equation Añ = is inconsistent. Then the following statements are true. A. The least squares solution to Ax = 6 is given by î = (A” A) A 5 B. We can reduce the least squares solution Î = (A” A)-'A” as follows. î = (A” A)'AT = Â = A-'(AT)-'A" 6 = This calculation follows since when matrices A = QR where Q = (ū ūk) and...
Suppose that А is an mxn matrix with independent columns and the equation Az = 7 is inconsistent. Then the following statements are true. A. The least squares solution to AT = 5 is given by î = (A” A) "A" 7 B. We can reduce the least squares solution Î = (A" A) "A" 5 as follows. î = (A" A) "A" 5 = = A** (AT) 'A 5 = This calculation follows since when matrices This calculation follows...
Suppose А is an mxn matrix having independent columns and we have the factorization A = QR Then if DER" and b = Proje , we can write the solution to A² = as * = R'0". Hint: Recall that for matrices C and D , we have (CD)' = "C" True False Let w be a subspace of the vector space R" . Identify which of the following statements are true. A. We have that W! is a subspace...
