Create the following matrix M: 1 7 13 19 25 ?-3 9 15 21 27 5 11 17 2329By writing one command and using the colon to address ran
zimovet [89]

Answer:

Matlab code is:

>> M=reshape(1:2:29, 3,5)

>> \%  (a)

>> Va=M(3,:)

>> \% (b)

>> Vb=M(:,4)

>> \% (c)

>> Vc=[M(2,:) M(:,3)']

Explanation:

>>\% \ Making\ the\ Matrix\ With\ required\ terms\ 1\ to\ 29\ with\ spaces\ of\ 5\ in\ three\ rows

>> M=reshape(1:2:29, 3,5)

M =

              1   7  13  19  25

              3  9  15  21  27

              5  11  17  23  29

>> \%  (a)

>>\%\ Slicing\ M\ \ from\ third\ row\ till\ end

>> Va=M(3,:)

Va =\\\ 5\ 11\ 17\ 23\ 29

>> \% (b)

>>\% \ Slicing\ the\4th\ column\ of\  M\ matrix\

>> Vb=M(:,4)

Vb =\\ 19\\ 21\\ 23\\

>> \% (c)

>>\% \ slicing\ the\ 2nd\ row\ and\ 3rd\ column\ of\ M\ Matrix\ and\ combining\ them\ to\ make\ a\ row\ matrix

>> Vc=[M(2,:) M(:,3)']

Vc =\\ 3\ 9\ 15\ 21\ 27\ 13\ 15\ 17

>>

The code is tested and is correct. If you put a semi colon ' ; ' at the end of every statement then your answer will be calculated but matlab doesn't show it until you ask i.e. typing the variable (Va, Vb, Vc )and press enter.
