Generate a matrix A by setting
A = floor(10 * rand((6))
and generate a vector b by setting
(a) Since A was generated randomly, we would expect it to be nonsingular. The system
(b) Let us now change A so as to make it singular.

- Let A be an nn matrix in which the entries of each row sum to zero. Find |A|.arrow_forwardFind the sequence of the elementary matrices whose product is the non singular matrix below. [2410]arrow_forwardCan a matrix that has 0 entries for an entire row have one solution? Explain why or why not.arrow_forward
- Referring to Exercise 19, suppose that the unit cost of distributing the products to stores is the same for each product but varies by warehouse because of the distances involved. It costs $0.75 to distribute one unit from warehouse 1 and $1.00 to distribute one unit from warehouse 2. Organize these costs into a matrix C and then use matrix multiplication to compute the total cost of distributing each product.arrow_forwardCan a matrix with an entire column of zeros have an inverse? Explain why or why not.arrow_forwardShow that the matrix below does not have an LU factorization. A=0110arrow_forward
- Explain the difference between the row-echelon form and the reduced row-echelon form of a matrix.arrow_forwardDetermine if the statement is true or false. If the statement is false, then correct it and make it true. For the product of two matrices to be defined, the number of rows of the first matrix must equal the number of columns of the second matrix.arrow_forward
