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

You should not use square braces.. a[1] not allowed.
Use a(1)
a= [3.4 -4.90 0.23] ;
a(1)
a(end)
