Using Matlab

Matrix indexing using integer arrays (get/set values of multiple elements in a 2D array): deleting elements using]: indexing using a single colon (:) and end keyword. Referring and modify matrices - Given a matrix, mat. Dothefollowing in order shown below o The matrix mat will be randomized at each submission, and will be created by Create a new row vector with values from the second row of mat. Assign this vector . Create a new column vector with values from the second to last column of mat. .Modify the 3rd and 5h rows of mat to the value 99. Make a new copy of mat, by .Modify the single element at the last row and the last column to -1. Make a new copy Swapping the 2nd column with the 1st column. Make a new copy, assigning mat as the auto grader. Do not modify the given matrix mat. to variable answer 1 Assign this vector to variable answer 2 assigning mat as variable answer 3 assigning mat as variable answer 4 variable answer 5 o Hint: Try and adapt from the example below test [10 20 30; 40 50 60] . >> test ( [2, 1],:) = test ( [1, 2],") .Removing the last column from mat. Make a new copy, assigning mat to the variable answer 6. o Hint: Use the empty matrix notation, [] Example: The expected answers for one example of mat are shown below mat answer1 answer2 8 10 13 14 15 14 answer 3 answer 4 answer6 answer 5 3 10 11 12 10 11 12 11 10 12 11 10
