-% [PYR, INDICES, STEERMTX, HARMONICS] = buildSCFpyr(IM, HEIGHT, ORDER, TWIDTH)
-%
-% This is a modified version of buildSFpyr, that constructs a
-% complex-valued steerable pyramid  using Hilbert-transform pairs
-% of filters.  Note that the imaginary parts will *not* be steerable.
-%
-% To reconstruct from this representation, either call reconSFpyr
-% on the real part of the pyramid, *or* call reconSCFpyr which will
-% use both real and imaginary parts (forcing analyticity).
-%
-% Description of this transform appears in: Portilla & Simoncelli,
-% Int'l Journal of Computer Vision, 40(1):49-71, Oct 2000.
-% Further information: http://www.cns.nyu.edu/~eero/STEERPYR/
-
-% Original code: Eero Simoncelli, 5/97.
-% Modified by Javier Portilla to return complex (quadrature pair) channels,
-% 9/97.
