Lines Matching full:nonzero
526 * nonzero coefficients in the block, because otherwise we'd get confused
527 * next time about which coefficients were already nonzero.
528 * But we need not undo addition of bits to already-nonzero coefficients;
546 s = p1; /* newly nonzero coef is positive */
548 s = m1; /* newly nonzero coef is negative */
561 /* Advance over already-nonzero coefs and r still-zero coefs,
585 /* Output newly nonzero coefficient */
595 * (the last newly nonzero coefficient, if any). Append a correction
596 * bit to each already-nonzero coefficient. A correction bit is 1
628 /* Re-zero any output coefficients that we made newly nonzero */
