A vector x containing values { 1 , 2 , 3 , 4 } is entered by using the following command: >> x=[1 2 3 4] Here, x is a row vector. It can be changed into a column vector by: >> x=[1; 2; 3; 4] Alternately, a row vector x , can be changed into a column vector or viceversa by sim ply issuing the following command: >> x’ Here, ’ represents transpose. All the elements of x can be multiplied or divided by 2 by issuing the following commands: >> 2*x >> x/2 Let x = [1 2 3 4] and y = [5 6 7 8]. Suppose we want to multiply the first element of x with the first element of y , second element of x by the second element of y , and so on. This can be accomplished by using the following command: >> x.*y Notice the . in the above command. This represents element by element operation....
