Miscellaneous Functions for Dual-Tree Wavelet Software

Miscellaneous functions for dual-tree wavelet software.

cshift(x, m)
cshift2D(x, m)
pm(a, b)

Arguments

x	\(N\)-point vector
m	amount of shift
a,b	input parameters

Value

y

vector \(x\) will be shifed by \(m\) samples to the left or matrix \(x\) will be shifed by \(m\) samples down.

u

\((a + b)/sqrt(2)\)

v

\((a - b)/sqrt(2)\)
