Name

wrcoef — Restruction from single branch from multiple level decompstion

Calling Sequence

X=wrcoef(type,c,l,wname,[N])
X=wrcoef(type,c,l,Lo_R,Hi_R,[N])

Parameters

type
: approximation or detail, 'a' or 'd'.
wname
: wavelet name
X
: reconstruction
Lo_R
: lowpass synthesis filter
Hi_R
: highpass syntheis filter
c
: coefficent array
l
: length array
N
: restruction level

Description

wrcoef is for reconstruciton from single branch of multiple level decompostion. Extension mode is stored as a global variable and could be changed with dwtmode. If N is omitted, maximum level is used.

Examples

  x=rand(1,100);
  [C,L]=wavedec(x,3,'db2');
  x0=wrcoef('a',c,l,'db2',2);
