Matrices: Representation, Order and Types
State the order (rows x columns), read the requested element, count the elements, or name the type of each matrix.
- 1.State the order (size) of the matrix M = [9 3; 5 9].
- 2.State the order (size) of the matrix M = [6 1; 6 4].
- 3.State the order (size) of the matrix M = [4 2 5; 4 6 7; 7 8 8].
- 4.For the matrix A = [4 3 2; 5 4 9; 9 4 8], write down the element a(2,1), the entry in row 2, column 1.
- 5.For the matrix A = [4 2 1; 2 4 7; 7 3 4], write down the element a(3,2), the entry in row 3, column 2.
- 6.For the matrix A = [5 9; 2 7; 3 7], write down the element a(2,2), the entry in row 2, column 2.
- 7.How many elements does a 2 x 3 matrix have?
- 8.How many elements does a 2 x 4 matrix have?
- 9.What type of matrix is [7 1 4]? (row, column, square, zero, or identity)
- 10.What type of matrix is [4; 7; 7]? (row, column, square, zero, or identity)
- 11.What type of matrix is [5 3; 6 1]? (row, column, square, zero, or identity)
- 12.What type of matrix is [0 0; 0 0]? (row, column, square, zero, or identity)
