MATLAB

Concerning array manipulation: Enter the following (magical) matrix in MATLAB: MB|3 Using array indexing, compute the sum of the 2"d row of M 5 7 2 4 c. Using the diag function, compute the sum of the main diagonal of M. d. Using array indexing, copy the top middle value from M and store it in N. f Using array indexing, multiply each element of the first row of M by the g. Using array indexing, delete the middle column from M. Using array indexing, expand N to be a 1x4 vector by setting the values in the 2nd 3rd and 4th column of N equal to the last row of M. corresponding element of the 3rd column of M (8*6, 1*7, and 6*2). The result must be a column vector. Hint: You will have to use the transpose operator. h. Generate a 3x4 matrix called lucky that contains all 7s using one line of code and only typing "7" once
