Run forward and inverse slantlet transform
x = randn(1,2^5); s = slantlt(x); y = islantlt(s); % inverse transform max(abs(x-y)) % reconstruction error
ans = 1.1380e-15
Run shift invariant (over-sampled) slantlet transform.
x = sin(sin((1:2^5)/3)); s = sislet(x); y = isislet(s); % inverse transform max(abs(x-y)) % reconstruction error
ans = 2.2204e-16
Run two-dimensional slantlet transform
x = randn(2^5); s = slet2(x); y = islet2(s); % inverse transform max(max(abs(x-y))) % reconstruction error
ans = 2.2760e-15
