I want to use SVMStruct = svmtrain(Training,Group) for classification But each element in the Training matrix is represented by cell array so after run that I got this error :
*Error using svmtrain (line 241)
TRAINING must be a numeric matrix.*
Could anyone guide how to correct this error,thank you.

One way to convert cell array categories to numerical categories is illustrated by the followign example:
Training = {'A','B','B','A','C','C'};
uniqueTraining = unique(Training);
[~,numericalTraining] = ismember(Training,uniqueTraining)
