Lines Matching full:nonzero
531 * nonzero coefficients in the block, because otherwise we'd get confused
532 * next time about which coefficients were already nonzero.
533 * But we need not undo addition of bits to already-nonzero coefficients;
551 s = p1; /* newly nonzero coef is positive */
553 s = m1; /* newly nonzero coef is negative */
566 /* Advance over already-nonzero coefs and r still-zero coefs,
590 /* Output newly nonzero coefficient */
600 * (the last newly nonzero coefficient, if any). Append a correction
601 * bit to each already-nonzero coefficient. A correction bit is 1
633 /* Re-zero any output coefficients that we made newly nonzero */
