2Title Subtitle Subtle En ing Heading Paragraph Styles MATLAB PROGRAM 1. Create a variable a that is a row vector with the following elements: 9, 1,32, 7/4, o, 2.25 ×85.08, and sin(r/8). 3. Create a variable c that is a column vector with the following elements: 2.1 102, sin(.7a), 28.5, 2.7/3, ande. Create a variable h that is a row vector with eight equally spaced elements in which the first element is 68 and the last element is 12. 12. Using the linspace command, create a row vector (assign it to a variable named Fours) with nine elements that are all 4. 26. Create the following matrix by typing one command. Do not type individ- ual elements explicitly. 30. Create the following matrix by typing one command. Do not type individ- ual elements explicitly

Explanation / Answer

% ques 1

% sin() gives the value of sine()

a = [ 9 , 1 , 3 ^ 2 , 7 / 4 , 2.25 * 0.8 , sin( pi / 8 ) ]

% ques 3

c = [ 2.1 * ( 10 ^ -2 );

      sin( 1.7 * pi ) ;

      28.5 ;

      2.7 ^ ( 4 / 3 );

      exp(3)]

% create 8 equally spaced element between 68 and 12

h = linspace( 68 , 12 , 8 )

% ques 12

Fours = [ 4 , 4 , 4 , 4 , 4 , 4 , 4 , 4 , 4]

% ques 26

% ' is used to transpose the matrix

% repelem() is used to make vector of size 5 and each eleemnt 6 and 8

c1 = [ repelem( [ 6 ] , 5 );

       repelem( [ 8 ] , 5 ) ]'

  

G = [ repelem( [ 1 , 0 ] , 3 );

      repelem( [ 1 , 0 ] , 3 );

      repelem( [ 1 , 0 ] , 3 );

      repelem( [ 1 ] , 6 );

      repelem( [ 1 ] , 6 )]'
