y(i) = y(i) + 1;
instead of
y(II) = y(II) + 1;

The value of II may be a floatpoint number. MATLAB uses integer and 1 based indexing for accessing array elements

Due to floating point round-off, the result A+(B*x(i)) might not be exactly an integer. You should round() it.

You have not posted enough context to really give you an answer.
But I suspect that you should have made x one element shorter. Something along the line of
x = linspace(xmin, xmax, number_of_steps+1);
x = x(1:end-1);
