i have a problem to select every row.
i have matrix 100x13.
i want to select data which position in row 1-5, 21-25, 41-45, 61-65, 81-85.
so i have 2 new matrixs. first as i described above, and the second is the rest (6-20, 26-40, 46-60, 66-80, 86-100).
i want to apply k-fold method to get training data and testing data.
thanks a lot if somebody can help me.
A = rand(100,4);
ind_logical = logical(ones(100,1)); ind_logical([1:5, 21:25, 41:45, 61:65, 81:85])=false;
B = A(~ind_logical,:); C = A(ind_logical,:);
