Find value from column / row number

Hi,
I've vector A = [5, 7, 8, 11, 4, 5, 7]
Now, I want to know what is value in column number 3 and 5, hoping with results 11 and 4.
Can you help me get the script

Do you mean >>A(3) and >>A(5) Note: unlike python here indexing starts with 1,2,....

In MATLAB, array indexing uses integers greater than zero, so indices corresponding to your vector elements 11 and 5 would be 4 and 6, respectively.
If all you want to know is the value of a certain part of the matrix just call the index.
A(3)
A(3) = 8
You can call multiple things with indexing, and you can add logic statements to check for certain values as well if you would like.
