Hello All,
I've got an easy one for you:
I want to limit the x-axis on a plot from 0 to the total number of rows in the "A" vector. Code so far is:
xlim(0, ______ );
I'm going to file this one in the too-fried-at-the-moment category.

Assuming you’re plotting by indices:
axis([0 length(A) ylim])
or:
set(gca, 'XLim',[0 length(A)])
If you want to use the last value in ‘A’, replace ‘length(A)’ with ‘A(end)’ in those function calls.
