Fish Muscle Fluorescence EEM Data

Fluorescence measurements can reveal chemical changes in fish muscle during storage. CMA1_fluo.mat contains excitation-emission data from aqueous extracts of frozen-thawed, modified-atmosphere-packed cod fillets. AllSamples_X has shape 105 x 4303 (sample x unfolded fluorescence variables), with Axis1 providing 331 emission wavelengths from 270 to 600 nm and Axis2 providing 13 excitation wavelengths from 250 to 370 nm. design has shape 105 x 3 and records frozen-storage temperature, frozen-storage time code, and chill-storage time. The design covers 35 storage conditions with three replicates each.
