C Code Wavelet Transform and Explanation - Stack Overflow
WebI want to write continuous wavelet transform codes manually by matlab. And I want to use complex morlet function. Here are some background: Continuous wavelet transform definition: C ( S, T; f ( t), ψ ( t)) = 1 S ∫ S b f ( t) ψ ∗ ( t − T S) S is scale vector.for example 1:60; T is time slid. And ψ ( t) = 1 π f b e 2 π f c t e − t 2 f b Web21 de dic. de 2024 · We start with the beginning of our signal and slowly move the wavelet towards the end of the signal. This procedure is also known as a convolution. After we have done this for the original (mother) wavelet, we can scale it such that it becomes larger and repeat the process. This process is illustrated in the figure below. GIF property for sale far sawrey
