Hi Melissa,

sounds like homework. You find the answer here:

the 8th element the question is referring isit 3?

[Stephan]

?

[melissa tan]

huh?

[Walter Roberson]

Read about linear indexing.

Melissa - we do not do homework here for others. This also includes your homework. I gave you a link - read it. Then try it in Matlab and see what happens. If you get stuck by trying it - here is the right place to ask. But you have to show us that you have tried it.

 A=[0 2 0 4 5 ; 1 20 3 40 5 ;10 200 30 40 50]

A =

     0     2     0     4     5
     1    20     3    40     5
    10   200    30    40    50

>> A(2,3)

ans =

     3
is this correct?

[Stephan]

Yes

Doesn't look like you read about linear indexing like Walter suggested. Did you look at A(8)?

[Stephan]

Why are you so unconfident If you Type A (8) and get 3 as result. And you type A (2,3) and get 3 as result. Look at your matrix. How many 3 are there? What can you conclude from this? Read the link
