I have loaded a dataset, there are three classes as follows:
and I need to have the corresponding label set in order to training data with LSTM, but I don't know how to get a N*1categorical array like this:
How can I do this? I really need your help.

We can create categorical arrays using the categorical function.
Assuming SR, VF, and VT are cell arrays of character vectors we can call categorical with a value set. For example,
% Example data
SR = {'N','A','N','N'};
VF = {'N','N','N'};
VT = {'A','N'};
% Convert SR, VF, and VT into categorical arrays
valueset = {'N','A'};
SR = categorical(SR,valueset)
VF = categorical(VF,valueset)
VT = categorical(VT,valueset)
Assuming SR, VF, and VT are NOT cell arrays of character vectors, but can be concatenated, we can call categorical with a value set and a set of corresponding category names. For example,
% Example data
SR = {0,1,0,0};
VF = {0,0,0};
VT = {1,0};
% Convert SR, VF, and VT into categorical arrays
valueset = [0 1];
catnames = {'N','A'};
SR = categorical([SR{:}],valueset,catnames)
VF = categorical([VF{:}],valueset,catnames)
VT = categorical([VT{:}],valueset,catnames)
