Problem in svmtrain : Help

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)

the cyclist: Thank you very much,I have Training matrix 1*40 cells,and each cell is 75 rows * 10 columns,so I want to give this Training matrix to the svmtrain function but I got this error :

Error using svmtrain (line 241)

TRAINING must be a numeric matrix.*

Could you guide me how to correct this error,thank you.
