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.
