runSGWT: Run SGWT forward and inverse transforms for all signals

In BioGSP: Biological Graph Signal Processing for Spatial Data Analysis

Run SGWT forward and inverse transforms for all signals

Description

Perform SGWT analysis on all signals in the SGWT object. Uses batch processing for multiple signals when possible for efficiency. Assumes Graph slot is populated by runSpecGraph().

Usage

runSGWT(SG, use_batch = TRUE, verbose = TRUE)

Arguments

SG	SGWT object with Graph slot populated
use_batch	Whether to use batch processing for multiple signals (default: TRUE)
verbose	Whether to print progress messages (default: TRUE)

Value

Updated SGWT object with Forward and Inverse slots populated

Examples

# Create example data
data <- data.frame(x = runif(100), y = runif(100), signal = rnorm(100))
SG <- initSGWT(data, signals = "signal")
SG <- runSpecGraph(SG, k = 15)

# Uses batch processing by default
SG <- runSGWT(SG)

# Or force individual processing
SG2 <- initSGWT(data, signals = "signal")
SG2 <- runSpecGraph(SG2, k = 15)
SG2 <- runSGWT(SG2, use_batch = FALSE)
