Name

wrcoef2 — Restruction from single branch from two dimension multiple level decompstion

Calling Sequence

X=wrcoef2(type,c,s,wname,[N])
X=wrcoef2(type,c,s,Lo_R,Hi_R,[N])

Parameters

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

Description

wrcoef2 is for reconstruciton from single branch of two dimension 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(100,100);
  [C,S]=wavedec2(x,3,'db2');
  A2=wrcoef2('a',c,S,'db2',2);
