I have 3 classes and each class contain 2000 sample of .mat. for example
2PSK
fram2psk1.mat, fram2psk2.mat, fram2psk3.mat, fram2psk4.mat, ......... fram2psk2000.mat,
4PSK
fram4psk1.mat, fram4psk2.mat, fram4psk3.mat, fram4psk4.mat, ......... fram4psk2000.mat,
8PSK
fram8psk1.mat, fram8psk2.mat, fram8psk3.mat, fram8psk4.mat, ......... fram8psk2000.mat,

sir,may be use cell to save the data in mat file,such as
[XTrain,YTrain] = japaneseVowelsTrainData
XTrain = 270×1 cell array
{12×20 double} {12×26 double} {12×22 double} {12×20 double} {12×21 double} {12×23 double} {12×22 double} {12×18 double} {12×24 double} {12×15 double} {12×23 double} {12×15 double} {12×17 double} {12×14 double} {12×14 double} {12×15 double}
YTrain = 270×1 categorical array
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
