how to convert a numeric matrix to cell array without changing its property?

i have a training matrix A of dimension 384x4160, inorder to create labels and supply it as a input to the svmtrain function, i have converted the matrix to a cell array using the following command,

train_cell={train(1:64,:),train(65:128,:),train(129:192,:),train(193:256,:),train(257:320,:),train(321:384,:)};

it has given me a 1x6 cellarray say (B) of the following dimension,

64x4160 double  64x4160 double  64x4160 double  64x4160 double  64x4160 double  64x4160 double

As per the svm documentation the train matrix must be a numeric array, but after the conversion of matrix to cell array using the above command, the cellarray becomes non-numeric. i.e when i give

isnumeric(train_cell)

the answer is,

ans =

logical

   0

Kindly, suggest me how to convert the matrix to cellarray by holding its numeric property.

You can't. A cell array is by definition a cell array, while only numerical arrays are numerical arrays.

 As per the svm documentation the train matrix must be a numeric array, ...

Exactly. Then a conversion to a cell is not a valid option.

What is the actual problem you want to solve? What does this exactly mean: "in order to create labels and supply it as a input"?
