Question

Can someone help me to solve it by Matlab?

7. Create a 5 row, 8 col matrix called mymat w ith random integers betwee n and including 70 and 90 Create a matrix from mymat called newmat whose entries consist of those entries which are both in the second and third rows, but also in the 4th through 6th columns 8. 9 What command would you type to list just the 4th row, 6th column entry of mymat? 1o. Crete variable calef ny wich s the sum of mmats row entries 11. Create matrix called sar which has 8 rows and 8 columns, and whose entries are random floating point numbers between 21 and 37. 12. Create a variable called dmy which is the sum of sar's diagonal entries.

Answer 1

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

mymat=randi(21,5,8)+69
newmat=mymat(2:3,4:6)
mymat(4,6)
smy=sum(mymat(3,:))
sqr=rand(8,8)*16+21
dmy=sum(diag(sqr))

Kindly revert for any queries

Thanks.
