Use Matlab command to obtain the following:. a) Extract the fourth row of the matrix generated by magic(6)
b) Show the results of ‘x’ multiply by ‘y’ and ‘y’ divides by ‘x’. Given x = [0:0.1:1.1] and y = [10:21]
c) Generate random matrix ‘r’ of size 4 by 5 with number varying between -8 and 9

Using Matlab command

a)  

displaying fourth row after generating a magic matrix of 6*6

%generate matrix magic(6)

magic6 = magic(6);

disp ('This is Magic(6): ');

disp (magic6);

%Obtain the fourth row elements of magic6

fourthRowMagic6 = magic6(4,:);

disp('This is the 4th Row of Magic 6:');

disp(fourthRowMagic6);

b)

first we create a vector with values 0 --> 1.1 with increment of 0.1 and vector b with values 10 > 21 with increment of 1 value.

now

%creating and array x

x=[0:0.1:1.1];

y=[10:21];

%x multiply by y

multip_xy = x.*y;

%y divide by x

div_yx = y./x;

%display Text

disp('x: ');

disp(x);

disp('y: ');

disp(y);

disp('Multiplication of ''x'' and ''y'' is: ');

disp(multip_xy);

disp('Division of ''y'' and ''x'' is: ');

disp(div_yx);

c)

randi[] fuction creates integer random values in given range.

% creates a random matrix of four rows and five  columns varying between -8 and 9

r=randi([-8 9], 4,5);

disp('Here is a random 4 by 5 matrix varying between -8 and 9 ');

disp(r);

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
