Hello,

I currently research the field of near-infrared spectroscopy (NIR), mainly in the analysis of the spectra of polymeric materials. I would like to make a system for classifying these spectra by machine learning. Literature indicates the APP Classification Leaner and its models to perform the training of the spectra. However, I’m having trouble inserting the spectra sheet (containing wavelength and absorbance values). Being new to Matlab, I don’t know how to organize these spreadsheets with different values, because the wavelength is constant for the different samples, but the absorbance varies for them. My idea is to classify the spectra for the different materials. How could I organize the spreadsheet and develop the training?

If anyone can help me with a tutorial or quick step by step, I would be extremely grateful.
