Essentially, wavedec
calls dwt
function (NWaves equivalent: Fwt.Direct()
);
wrcoef
calls idwt
function (NWaves equivalent: Fwt.Inverse()
).
// x is input array
var C_L = new float[x.Length]; // for decomposition results
var A_D = new float[x.Length]; // for reconstruction results
var fwt = new Fwt(x.Length, new Wavelet("db5"));
int level = 9;
fwt.Direct(x, C_L, level);
fwt.Inverse(C_L, A_D, level);
I've also added another overloaded constructor in Wavelet
constructor accepting custom coefficients
var fwt = new Fwt(x.Length, new Wavelet(lo_dec, hi_dec, lo_rec, hi_rec));
//...
