From 9d9a208571db55b790ea9f0ae2109ed9f1e31b1e Mon Sep 17 00:00:00 2001 From: JaredW40 Date: Thu, 2 Apr 2026 00:15:58 -0700 Subject: [PATCH 01/10] Adjusted CWT's default `averagingLength` to match the description. New `getUpperBound` function for Morse wavelets, using `getMean` function. In `createWavelets.jl,` retired original father function for Morse in favor of a Dirac lowpass method instead (was producing negtives when used for averaging. New version does not). --- src/CWTConstruction.jl | 3 ++- src/createWavelets.jl | 11 +++++++++-- src/utils.jl | 5 ++++- 3 files changed, 15 insertions(+), 4 deletions(-) diff --git a/src/CWTConstruction.jl b/src/CWTConstruction.jl index 6e30242..1544369 100644 --- a/src/CWTConstruction.jl +++ b/src/CWTConstruction.jl @@ -58,11 +58,12 @@ end CWT(wave::ContWaveClass, Q=8, boundary::WaveletBoundary=SymBoundary(), averagingType::Average = Father(), averagingLength::Int = 4, frameBound=1, p::N=Inf, β=4) """ +defaultAveragingLength(::ContWaveClass) = 4 function CWT(wave::WC, Q = 8, boundary::B = DEFAULT_BOUNDARY, averagingType::A = Father(), -
