Figure 7From: Multivariate matching pursuit in optimal Gabor dictionaries: theory and software with interface for EEG/MEG via Svarog Optimal scale factor, frequency step and position step. Optimal scale factor a (top plot—see Eq. (20)), frequency step Δω (middle plot—see Eq. (22)) and position step Δu (see Eq. (24)) as a function of ω for three values of ϵ and scale s=10.Back to article page
