%description
Traditional methods typically detect breakpoints from individual signals,
which means that when applied separately to multiple signals, the
breakpoints are not aligned. However, this package implements a common
breakpoint detection approach for multiple piecewise constant signals,
resulting in increased detection sensitivity and specificity. By employing
various techniques, optimal performance is ensured, and computation is
accelerated. We hope that this package will be beneficial for researchers
in signal processing, bioinformatics, economy, and other related fields.
The segmentation(), lambda_estimator() functions are the main functions of
this package.
