Cholesky multivariate decomposition algorithm for infrared spectrometric determination of active components in laundry detergent powder Full Paper
A new calibration method based on of Cholesky decomposition (CD) has been introduced. It is the decomposition of a positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose. This approach has been utilized to overcome the problem of serious spectral overlapping during the infrared spectrometric determination of sodium tripolyphosphate, sodium sulfate and sodium carbonate in laundry detergent powders. Comparing the root mean square error of prediction infatcat:rmmhpgejfbhydjkqkzjndae4pu
