the previous code is int Y_predict[N,K]; should I change it to array[N,K] int Y_predict; or matrix[N,K] int Y_predict;?

The first one is correct [image] liamxg: array[N,K] int Y_predict; There’s a similar discussion in How to declare a integer-valued matrix? - #4 by Xavier_La_Rochelle

Int Y_predict[N,K];
