Show us the complete code..you tried.

Answer 1

In MATLAB, we access the elements of an array using paranthesis () and not square brackets [ ]. You can see an example below :

arr =[3.4 -4.90 0.23];
arr(1)=3.4  % using arr[1] would lead to error as in your case
arr(2)=-4.90
arr(3)=0.23

I have already answered it.

Yeah , great . We are allowed to put our independent views on the question.

Answer 2

You should not use square braces.. a[1] not allowed.

Use a(1)

a= [3.4 -4.90 0.23] ;
a(1)
a(end)
