Just for clarification, there are two ways to deal with it: either start at the end and work backwards (for i=sizeX:-1:1 ; for j=sizeY:-1:0 ; abc_p(i,j)=...; end; end    or simply preallocate the last element   abc_p(sizeX,sizeY)=1 before the loop (it will presumably be overwritten with the correct value later, but the array will be preallocated to full size).

Thank you suggesting that; it never hurts to have multiple solutions. I think I've done it both ways on some occasion or another, but usually I find it more natural just to do something like abc_p = zeros(sizeX,sizeY).
