1) Use THREE different methods to create the following row vector. 6.9000 5.7000 4.5000 3.3000
2) Type a Matlab expression to create a column vector that has values from -30 to 40 in step of 0.5.
3) Write Matlab expressions to generate a 7 (row) x 6 (col) matrix variable mat with all zeros. Then (1) replace the third row with all "3"s, (2) replace the 2nd column with a new vector: [1, 4, 7, 10, 13, 16, 19]
4) Write Matlab expressions to create a 5 x 4 matrix of integer random numbers in the inclusive range from 50 to 80. Then write three Matlab expressions to: . Find the maximum value in each column. . Find the maximum value in each row. Find the maximum value in the entire matrix.
