1. 数据预处理：使用 Matlab 中的工具箱对原始光谱数据进行预处理，例如去除基线、波长校正、光谱平滑、...
算法底层基于公式，可赋予变量物理意义，如原始混合物光谱数据矩阵、行方向纯组分光谱、列方向纯组分光谱和噪音/无法解析数据。理解MCR-ALS算法难点在于证明D=CS^T+E。通过高效液相色谱吸收光谱分析示例，假设一次测量中总保留时间为T，n次测量，m种波长，[公式]种纯净物组成体系，假设无误差，定义数据矩阵...
MATLAB toolboxA new graphical user-friendly interface for Multivariate Curve Resolution using Alternating Least Squares has been developed as a freely available MATLAB toolbox. Through the use of this new easy-to-use graphical interface, the selection of the type of data analysis (either individual...
This GUI works under MATLAB® environment and includes recent published advances of this algorithm linked to the implementation of additional constraints, such as kinetic hard-modeling and correlation (calibration), as well as constraints linked to model structure for multiset and multi-way data ...
请问虫友们，有谁知道“多元曲线分辨-交替最小二乘（MCR-ALS)”matlab源代码或者是下载的网址，谢谢！
The second-order EEFMs data processing involving PARAFAC analysis was performed in Matlab2011a environment using a MVC2_GUI [50], freely available online [54] under only non-negativity constraint in all three modes (the sample, excitation and emission modes) using direct trilinear decomposition for...
The UV spectra of all samples were scanned over the wavelength range of 200–400 nm with data points collected every 1 nm, and the data were exported into Matlab for the following handling for the MCR-ALS model. Five components were used for MCR-ALS determination of all analytes. 2.4...
The data were exported into Matlab for developing the MCR-ALS model in which five variables were used for all the studied analytes. Table 1. Concentration matrix (μg/mL) used for the calibration set of the studied drugs. MixturePARASACAFNPXIPF 1 3.8 8.0 1.8 2.0 8.0 2 3.8 1.0 0.5 3.5 ...
