BLEMS ercises that foll Manipulating Matrices 41 Create the following matrices, and use them in the ex 15 3 22 a=| 3 8 51b=15|c=[12 1852] 14 3 82 (a) Create a matrix called d from the third column of matrix a. (b) Combine matrix b and matrix d to create matrix e, a two-dim o-dimensional matrix with three rows and two columns. (c) Combine matrix b and matrix d to create matrix f, a one-dimensional matrix with six rows and one column. (d) Create a matrix g from matrix a and the first three elements of matrix with four rows and three columns. (e) Create a matrix h with the first element equal to a1,3, the second element equal to q,2, and the third element equal to b21. shown in Table P4.2 and name it thermo_scores.

Explanation / Answer

(4.1)

%%% Matlab code %%%

clc;
clear all;
close all;
a=[15 3 22;3 8 5;14 3 82];
b=[1 5 6]';
c=[12 18 5 2];

%%% a)

disp('Matrix d is : ');
d=a(:,3)

%%% b)
disp('Matrix e is :');
e=[b d]

%%% c)
disp('Matrix f is :')
f=[b;d]

%% d)
disp('Matrix h is :');
h=[a(1,3) c(1,2) b(2,1) ]

OUTPUT:

Matrix d is :

d =

22
5
82

Matrix e is :

e =

1 22
5 5
6 82

Matrix f is :

f =

1
5
6
22
5
82

Matrix h is :

h =

22 18 5
