Interval Correlation Optimized Shifting (iCOshift) for fast, robust signal alignment across samples.
It implements all-at-once model for coupled matrix and tensor analysis (CMTF and ACMTF), enabling joint analysis of matrices + higher‐order tensors.
XYOnion: a layer-based method for splitting datasets into calibration and validation subsets.
Creates a combined PCA plot with scores, loadings, and violin plots to visualize sample groups, variable impact, and distributions.
This code recovers saturated signals using O-ALS by treating saturated signal as NaNs and reconstructing them from PCA subspace.
Legacy weighted SIMPLISMA (pure) for selecting pure variables in multivariate datasets.
MATLAB code to align images and hyperspectral images using shift, rotation, and scaling parameters.
MATLAB codes to access Renishaw WiRE .wdf Raman data files, with read/write access to spectra, mapped data, and header metadata.
MATLAB user-friendly GUI toolbox implementing MCR‑ALS with advanced constraints.
Hyper-Tools v.3.0. is a Graphical User-friendly Interface (GUI) for the analysis of multispectral and hyperspectral images.
