SOM Toolbox Online documentation neural_gas [Neurons] = neural_gas(D,n,epochs,alpha0,lambda0) NEURAL_GAS Quantizes the data space using the neural gas algorithm. Neurons = neural_gas(D, n, epochs, [alpha0], [lambda0]) C = neural_gas(D,50,10); sM = som_map_struct(sD); sM.codebook = neural_gas(sD,size(sM.codebook,1),10); Input and output arguments ([]'s are optional): D (matrix) the data matrix, size dlen x dim
