It's always recommended to avoid loops in Matlab whenever possible. Loops are much much slower than vectorized expressions. For example, the above loop from Romasa can be substituted single expression
x=A(1:10);
Bracket both into tic ... toc to see time difference.
Although I must say that sometimes loops are unavoidable or vectorization may requires more complex algorithm logic.

You can get the first value by statement A(1). You can assign it to another variable by b=A(1);
Use semicolumn (;) at the end of statement if you don't want matlab to display the output.
To access the last value you can use A(end). To access any sequence in any order if you use vector of indices, for example A([5 1 3]) will return vector [5 1 3].
