Question

7. (5 points) Create a 4x6 matrix of random integers, each in the range from -5 to 5; store it in a variable, ΥΧ. (a) Find the absolute value of rx. (b) Find the smallest and highest numbers in rx. (c) Find the sum of the row and sum of the columns of rx. Hint: use abs, min, max, and sum.

Answer 1

Script :

randi (-5 5],4,6) % this will create random matrix of 4x6 . 1 - rx = 2 8 a) To find Absolute value 3 abs (rx) 4 ABS= 8 b) To find out max. and min. value 6 min (rx )) =max ([rx () 1) Min 7 8 Маx 9 % c) To find the Sum of Row and Column 10 Sum of Columns Scol sum (rx) 11 - Srow sum (rx, 2) O Sum of rows 12 13 14 ос C

Command Window :

Command Window this will create random matrix of 4x6 randi -5 5] ,4, 6) >>rx a) To find Absolute value abs (rx) ABS b) To find out max. and min. value min (rx ] = max ([rx ()1) Min Маx 0% c) To find the Sum of Row and Column Scol sum (rx) % Sum of Columns Srow % Sum of rows sum (rx, 2) rx = -3 5 -1 0 -4 0 -5 1 -2 2 -4 -2 3 5 2 2 -4 -3 5 -1 2 -5 ABS 3 5 1 5 4 0 5 1 2 5 2 3 5 2 2 4 5 3 1 2 4 Min -5 O NN LO

Маx = Scol 0 0 4 7 0 -8 Srow 2 1 -6 LC Il LO

Code :

rx = randi([-5 5],4,6) % this will create random matrix of 4x6 .

% a) To find Absolute value
ABS = abs(rx)

% b) To find out max. and min. value
Min = min([rx(:)])
Max = max([rx(:)])

% c) To find the Sum of Row and Column
Scol = sum(rx)   % Sum of Columns
Srow= sum(rx,2) % Sum of rows
